Objectives

- Knowledge and understanding: The course aims at introducing the principles and the methodologies of spectroscopic techniques (rotational, vibrational and X-ray fluorescence spectroscopies) that are essential for the study and understanding of the structure and physico-chemical properies of molecules. Knowledge and understanding are achieved through lectures in a classroom, numerical exercises, laboratory activities and personal and guided study.

- Applying knowledge and understanding: The course provides the tools to use the acquired knowledge in the spectroscopic field for acquiring information on the structure and physico-chemical properties of molecules. These skills are mainly achieved by preparing and carrying out laboratory activities. The verification of the ability to apply deductive reasoning and the ability to interpret the data takes place during the execution of experiences in the laboratory and during the exam.

- Making judgements: The course aims at developping the capacity for critical reasoning, in particular the ability to critically interpret and evaluate the experimental data collected during laboratory exercises, to design and conduct experiments and to formulate solutions to analytical problems. The autonomy of judgment and the abilities above-mentioned are developed mainly in the laboratory exercises and verified both during the laboratory activities and through the drafting of reports.

- Communication: Communication skills are continuously stimulated in the classroom and in the laboratory, encouraging students to intervene publicly to improve their ability to describe in a clear and understandable manner any doubts and / or requests for clarification on specific topics. The student must be able to process and present experimental data also with the help of multimedia systems, possess the ability to expose their knowledge and their convictions ( both orally and through a scientific report) in a clear and critical way, with appropriate scientific language and with rigor of arguments. Finally, during the lab exercises, students will also be encouraged to develop their skills to work in groups.

- Lifelong learning skills: The course aims at developping the skills necessary to complete the studies of Chemistry, to apply the spectroscopic knowledge to different contexts, understand the limits of their knowledge and the ability to identify the Italian or English textbooks and other useful materials to acquire new skills and for continuous updating.

Prerequisites

The student must have achieved a good preparation in the previous courses in chemistry, physics and mathematics and have a good knowledge of scientific computing.

In order to take the exam, the student must have passed the exams of: Mathematic I, Physics I, Inorganic chemistry and laboratory, Organic Chemistry I, and Laboratory of Organic Chemistry II.

** X-ray fluorescence spectroscopy : principle and instruments


Laboratory Exercises (48 hours)
The students, divided into groups, carry out theoretical and numerical practical exercises, using spectrometers supplied by the didactic laboratories, with regard to problems of interest for the study and understanding of the structure of molecules.

Teaching Methods

The teaching method includes lectures (16 h) in the classroom and practical exercises in the laboratory (48 h).

Lectures in the classroom include an oral presentation performed through illustrative material during which the students are guided to the understanding of the basic concepts and applications of the main spectroscopic techniques essential for the study and understanding of the structure of molecules.
Each lesson is structured as follows:
• an introduction, which includes a clear presentation of the objectives, the key ideas and their relation to the objectives of the entire course. The fundamental aims of the introduction are to consolidate attention, reinforce motivation and provide an overview of what will be subsequently developed;
• a development, which presents the contents in detail in order to highlight the connections between the ideas or the key points;
• a conclusion, or summary, that welds together the whole. The conclusion is intended to reinforce learning and to reconnect the contents of the lesson with the general objectives.

The exercises in the laboratory are preceded by a description of the lesson: contents of the exercise, purpose, methods of execution, data analysis. The results obtained in each experience are discussed in the laboratory and in the classroom and are reported by each student in written reports that make up the laboratory notebook. The frequency of the laboratory part is mandatory.

NOTE: To meet specific needs related to the epidemiological situation, lessons could be attended in live streaming or recorded and then get available online. In addition, laboratory exercises could be attented in turn or replaced by online activities

Verification of learning

The exam mark is calculated as the weighted average of the evaluations obtained for: a written test*; an oral test*; the reports on the laboratory experiences; global skills in the laboratory.

Passing the written test is valid for 1 year.

* To deal with the epidemiological emergency, the two tests could be held in Microsoft Teams.

EVALUATION OF:

**THE LABORATORY REPORT:
28-30: The reports correctly describe the experience. The form is correct. There are no sections copied from other sources
25-27: The reports quite correctly describe the experience performed. The form has some errors. There are no sections copied from other sources
22-24: Reports do not accurately describe the experience. The form has some errors. There are sections copied from other sources
18-21: The reports describe the experience carried out in a superficial way. The form has several errors. There are sections copied from other sources

** GLOBAL CAPABILITIES IN THE LAB:
28-30: The student has carried out the experiences carefully, understanding the meaning of each operation. He/she has showed interest and initiative and good ability to work in groups. The workstation was neat and clean.
25-27: The student has carried out the experiences carefully, while not understanding the meaning of each operation. He/she has showed sufficient ability to work in groups and moderate interest. The workstation was not always neat and clean.
22-24: The student has carried out the experiences distractedly, not understanding the meaning of each operation. He/she has showed sufficient ability to work in groups and little interest. The workstation was lacking in order and cleanliness ..
18-21: The experiences carried out by the student were characterized by conceptual errors, not having achieved sufficient knowledge of the subject. He/she showed little interest and lack of ability to work in groups. The workstation was lacking in order and cleanliness

**WRITTEN AND ORAL EXAM:
a) 18-20 : The candidate demonstrates a few acquired notions, superficial level, many gaps, modest expressive abilities, however sufficient to sustain a coherent dialogue; logical skills and consequentiality in the connection of the elementary level topics; poor ability to synthesize and rather stunted graphic expression;
b) 21-23: The candidate demonstrates a discrete acquisition of notions, but little depth, few gaps; expressive abilities that are more than sufficient to sustain a coherent dialogue; acceptable mastery of scientific language; logical skills and consequentiality in the connection of the topics of moderate complexity; sufficient capacity for synthesis and acceptable graphic expression.
c) 24-26: The candidate demonstrates a rather broad baggage of notions, moderate depth, small gaps; satisfying expressive abilities and significant mastery of scientific language; dialogic ability and critical spirit that can be easily detected; good capacity for synthesis and graphic expression.
d) 27-29: The candidate demonstrates a wealth of notions, extensive, in-depth, marginal gaps; remarkable expressive abilities and elevated mastery of the scientific language; remarkable dialogical ability, good competence and relevant aptitude for logical synthesis; high capacity for synthesis and graphic expression.
e) 30: The candidate demonstrates a very extensive and in-depth knowledge of notions, any irrelevant gaps; high expressive abilities and high mastery of scientific language; excellent dialogic ability, strong ability to make connections between different topics; excellent capacity for synthesis and graphic expression.
The praise is attributed to candidates clearly above the average, and whose notional, expressive, conceptual, logical limits are generally totally irrelevant.
