Syllabus
*
1. Molecular structure Chemical bond(ionic, covalent), orbital hybridization. Theories of molecular orbitals (LCAO, Hückel method, bond order, length and energy). Structure of clusters. *
2. Determination of molecular structure Rotational and vibrational spectra. Franck-Condon principle. Cluster formation and dissociation, ionisation of clusters. Fluorescence, phosphorescence. Methods for determination of molecular spectra. *
3. Chemical reaction, reaction kinetics and dynamics Reaction cross section, reaction rate, rate coefficient, dependence on temperature, pressure. Direction of a reaction, equilibrium, equilibrium constants, catalysis, Le Chatelier’s principle. *
4. Experimental techniques Particle beams with low kinetic and internal energy - production, analysis and detection. Preparation of species in specific quantum state, Laser excitation and ionisation, multi-step excitation and ionisation, REMPI. Electron spin resonance, nuclear magnetic resonance. Collisional processes at cryogenic temperatures (collisional radiative recombination etc.).
