CY1020 Chemistry - I


Course Details

Fundamentals of Spectroscopy:
Electromagnetic spectrum, quantization of energy levels and regions of the spectrum resolution, line width and intensity. Basic principles and selected applications of: 1. Atomic spectroscopy : Absorption and emission types ? analysis of atomic constituents of a sample. Qualitative and quantitative analysis. Flame and plasma ionization, sources of atomic spectra, atomic absorption and fluorescence emission, identification of atomic spectral lines. 2. Microwave spectroscopy : Rotational energy levels of diatomic molecules, energy levels of spherical and symmetric tops, moment of inertia, calculations of bond lengths and bond angles of simple triatomic molecules. 3. Vibrational spectroscopy: IR and Raman spectroscopy: Harmonic oscillator, anharmonicity (Morse oscillator), normal modes of vibration, functional group identification, Raman effect, Stokes and anti-Stokes phenomena, selection rules for IR and Raman spectra, structure determination. 4. UV-Visible and Fluorescence spectroscopy: Electronic transitions, Franck-Condon Principle, spin and angular momenta, Term symbols, Beer-Lambert law, Jablonski diagram, excited state lifetime. 5. Electron spectroscopy of solids and surfaces: Photoemission, X-ray and UV photoemission spectroscopy, interpretation of photoelectron spectrum, Koopman?s Theorem, chemical shift. 6. NMR spectroscopy: Nuclear spin, gyromagnetic ratio, Larmor Frequency, chemical-shifts, anisotropic effects, spin-spin coupling, coupling constants, structure elucidation using 1H-NMR. 7. ESR spectroscopy: Electron spin, g-factor, hyperfine structure, applications in free radical. 8. Mossbauer spectroscopy: Nuclear transitions, resonant absorption, recoilless emission, isomer shift and quadrupole splitting .
