Exclusions
Description	The module examines in some depth the fundamental properties of molecules and how we observe them. Part A looks at how NMR spectroscopy can be used to not only determine the structure of a molecule but to probe how a molecule is affected by its surroundings. The next two parts of the course deal with how molecules behave after absorbing light in the visible / UV regions of the electromagnetic spectrum. Part B looks at how electronic spectroscopy can be used to probe the structure of bonding in diatomic molecules. Part C carries this topic on into how light effects changes in molecules in the field of photochemistry.
Learning Outcomes	By the end of the module students should be able to: Demonstrate an understanding of the (advanced) principles and concepts associated with the material delivered in each area; Apply their acquired knowledge to the solution of problems; understand where the NMR signal comes from and know what the macroscopic magnetisation and free induction decay are; understand what influences the frequency of a spinning nucleus, and what the Larmor frequency and origins of the chemical shift are; know how T1 and T2 relaxation affects the magnetisation; understand how the NMR signal is acquired and stored and what digitisation, spectral width, quadrature detection and the Nyquist theorem are; know what the relationship between time and frequency are and the basic principles of the Fourier transformation; use the vector representation to explain what happens to the macroscopic magnetisation after a 90˚ radio frequency pulse and how it is influenced by T1 and T2 relaxation; use the vector representation to explain how the pulse-acquire, Hahn (spin) echo, stimulated echo, inversion recovery and Carr-Purcell-Meiboom-Gill (CPMG) experiments work; understand the basic principles behind simple two-dimensional experiments such as polarsation transfer and exchange spectroscopy; understand how electron configurations of diatomic molecules can lead to bound and repulsive electronic states, and how the term symbol is derived; understand the basis of electronic spectroscopy and its selection rules; understand the vibrational and rotational structure observed in electronic spectra; understand the principles of photoelectron spectroscopy, and how it is an ‘experimental probe’ of the nature of the molecular orbitals of a molecule; understand how light interacts with a molecule; understand what a Jablonski diagram is; understand the kinetics of simple photochemical reactions; know what a potential energy surface represents; know the possible competing pathways open after photoexcitation; know the basic principles of how to convert light into energy and information and how to convert energy into light.
