UNIT – I CHEMICALKINETICS I:
Theories of reaction rate based on statistical mechanics –statistical mechanics and chemical equilibrium-Transition state theory based on statistical mechanicssymmetry numbers and statistical factors- transmission coefficient- reaction coordinate – potential energy surfaces – kinetic isotope effect – Hinshelwood theory – Kassel, Rice and Ramsperger theory (KRRT) – Slater’s treatment.
Principle of microscopic reversibility – steady-state approximation – chain reactions: thermal and photochemical reactions between hydrogen and halogens – explosions and hydrogen-oxygen reactions.
UNIT – II FAST REACTION TECHNIQUES, PHOTOCHEMISTRY AND RADIATION CHEMISTRY
Introduction – flow methods (continuous and stopped flow methods) – relaxation methods (T and P jump methods) – pulse techniques (pulse radiolysis, flash photolysis) – shock tube method – molecular beam method – lifetime method. Photophysical processes of electronically excited molecules – Jablonskidiagram Stern-Volmer equation and its applications – experimental techniques in
photochemistry – chemical actinometers – lasers and their applications. Differences between radiation chemistry and photochemistry – sources of high energy radiation and interaction with matter – radiolysis of water, solvated electrons – definition of G value, Curie, linear energy transfer (LET) and Rad – scavenging techniques – use of dosimetry and dosimeters in radiation chemistry – applications of radiation chemistry.
UNIT– III BASIC QUANTUM MECHANICS:
Inadequacy of classical mechanics – black body radiation – Planck’s quantum concept – photoelectric effect – Bohr’s theory of hydrogen atom – hydrogen spectra – wave-particle dualism – uncertainty principle – decline of old quantum theory. Schrödinger equation – postulates of quantum mechanics – operator algebra: linear operator, Hermitian operators, eigenfunctions and eigenvalues, angular momentum operator – commutation relations and related theorems – orthogonality and normalization.
Applications of wave mechanics to simple systems – particle in a box, one and three dimensional, particle with finite potential barrier – the quantum mechanical tunneling.
