general physics concepts as covered in LPHY1113 and physical chemistry as covered in LCHM1252
Main themes
The course of molecular spectroscopy will describe the different analysis techniques based on the interaction between molecules and an electromagnetic wave, as well as mass spectrometry. General physics courses are therefore a prerequisite, as well as the course in physical chemistry. The theoretical bases of different spectroscopic methods will be discussed during the lecture (30h). The identification of organic compounds from their spectra will be acquired during exercise sessions (20h). These notions are a basis for synthetic chemistry, and therefore for many subsequent courses as well as for research. The advanced courses directly related to this one are the "practical work supplements" CHM1300, "NMR complements" CHM2152 and "advanced mass spectrometry" CHM2151.

At the end of this learning unit, the student is able to :

1 At the end of this teaching and its evaluation, the student should be able to :
  1. describe the basic principle of any spectroscopy,
  2. explain the mode of operation, the advantages and disadvantages of each spectroscopy,
  3. distinguish in a scientific text (book, article) the contribution of a particular spectroscopic technique,
  4. extract the structure of an organic molecule from the interpretation of its IR, NMR, UV and mass spectra.

Teaching methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

Theoretical lectures including active pedagogy sessions are completed by exercise sessions given by an assistant.
Evaluation methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

The certification evaluation consists of a written examination in session.
