The current area of research is the study of vibrational and electronic spectra of the polyatomic molecules, bio- molecules and pharmaceuticals using experimental techniques (FTIR, Laser Raman Spectroscopy, UV- VIS Absorption Spectroscopy) and quantum chemical theories (HF, DFT, MP2). The anharmonic force field calculations (PT2 algorithm based on quadratic, cubic and semidiagonal quartic force constants and VSCF/ CC-VSCF methods) are used to study the molecular vibrational modes. The magnitudes of coupling strength between pairs of modes are a calculated using coupling integral based on 2MR-QFF approximation. The simulations on hydrogen bonded intermolecular complexes are also performed to investigate the effect of the intermolecular interactions on molecular structure, vibrational spectra and other molecular properties of monomer. NBO analysis is carried out for studying charge delocalization within the molecule and hydrogen bonded intermolecular interactions. In addition to these, TD-DFT/PCM calculations, NLO properties, MEP mapping, HOMO-LUMO analysis, reactivity descriptors, various thermodynamic properties have been also investigated at high level of theories. The journals in which our articles have been published are Spectrochimica Acta , Journal of Molecular Structure, Vibrational Spectroscopy, etc.Recently, we are also investigating structure and spectra of organic single crystal. Presently, I am teaching Laser Physics, Laser Spectroscopy and Molecular Spectroscopy, Experimental Techniques and Analytical Methods to postgraduate students.
