Syllabus
Atomic Structure: Hydrogen atom, quantum numbers, probability distribution of electron cloud in hydrogen atoms, orbital and spin angular momentum, spectroscopic term symbols for single electron system and atomic spectra (only fine structure of hydrogen & lithium atom), spectroscopic term symbols for multi electronic atoms (significance of L, S and J) and ground state term symbols Chemical Bonding: Valence bond theory and its limitation, molecular orbital (MO) theory, diatomic and polyatomic systems (concepts of s, p, non bonded orbitals), effect of conjugation. Molecular Term symbols. Molecular Interactions: Lennard Jones potential, intermolecular forces of attraction, classification of solids in terms of bonding (crystalline and amorphous solids, examples only), metallic bonding, introductory concept of conductors, semiconductors and insulators in terms of band gaps. Molecular spectroscopy: Spectral regions and molecular motions, elementary concepts of rotational (diatomic rigid rotor, selection rules) spectroscopy, molecular vibrations (qualitative treatment of simple harmonic and anharmonic oscillator, selection rules), fundamental modes of vibration (examples of H2O and CO2), Raman spectra (brief concept) for molecular vibrations only (examples of H2O and CO2), rule of mutual exclusion, electronic spectra (vibronic levels, absorption and emission), Beer-Lambert law, application in simple organic molecules.
Course Objectives
- The course aims to focus on the details of microscopic picture of matter.
Course Outcomes
Student would be expected to develop strong understanding of the macroscopic phenomena from a microscopic or molecular point of view.
