Notes and teaching material will be also provided by the teacher.

The goal is to provide a comprehensive introduction to the processes of interaction of light with various classes of molecular and supramolecular systems in the field of linear optics, with reference to the most recent scientific and technological applications. The fundamentals of vibrational and electronic spectroscopies, including time-resolved ones, will be covered. Examples of simulations of spectra of molecules in gas phase and in solution will be provided.
The classroom analysis of some topics of recent literature is foreseen in order to stimulate the students' independent critical sense.

It is strongly recommended the acquisition of the topics covered in the Mathematics I and II, Physics II and Physical Chemistry II courses

The course includes frontal lessons in the classroom where the treated topics will be presented and discussed with the students.
It will be given room for discussion with the students in order to stimulate both student learning and communication skills.
The collective analysis of some recent literature data will be useful to stimulate the autonomy of judgment and the critical sense of the students.
It is foreseen the collegial conduct of exercises dedicated to the interpretation of vibrational and electronic spectra to stimulate learning ability and autonomy of judgment.

The in itinere learning will be controlled by the execution of exercises in which the students have to show their knowledge in the interpretation of vibrational and electronic spectra.

The final oral exam will be aimed to verify the learning of the topics discussed during the lessons. Theoretical knowledge and interpretation of the electronic or vibrational spectra will be evaluated. The student's ability to use the tools provided in the lessons will be evaluated in order to interpret the vibrational and electronic spectra of organic and inorganic systems.
During the exam the communication skills will be evaluated also based on the language used by the student.
Excellence is achieved by demonstrating that the student has acquired all the elements covered in the course and demonstrating the ability to reason on real spectroscopic data.

Knowledge and understanding
Acquire solid knowledge that allows the recognition of organic molecules and inorganic systems; to know the interactions between molecules in the excited state, chiral systems and complex supramolecular systems.
Ability to apply knowledge and understanding
Acquire the ability to evaluate, in light of the notions learned during the course, which spectroscopic methods are most suitable depending on the type of sample; knowing how to interpret the effects caused by the interactions of molecules with other molecular systems, with solvents or with metal nanoparticles; If this will be taught in class through the collegial discussion of examples, during the exam it will be assessed by the request to describe real spectroscopic data.
Communication skills
Acquire and know how to use appropriate vocabulary in relation to the topics and spectroscopic techniques covered in the course. Know how to present the course topics in the oral exam.
Autonomy of judgement
Know how to critically analyze recent literature. It will be taught during the course through collegial discussions and requested during the exam phase through the discussion of literature topics.
Learning ability
Ability to use the teaching material for a critical and reasoned study, also for a subsequent independent acquisition of superior knowledge and for continuous updating.
