ALGEBRAIC APPROACH TO VIBRATIONAL SPECTRA OF TETRAHEDRAL MOLECULES - FIRST ORDER INFRARED INTENSITY MODEL

摘要

The algebraic approach we have proposed to describe the vibrational stretching modes of polyatomic molecules (Leroy and Michelot, J. Mol. Spectrosc. 151, 71-96 (1992); Can. J. Phys. 72, 274-289 (1994)) is applied to the silane molecule for up to seven quanta. We then suggest a form of the dipole operator adapted to the (n000) local states by combining the strength of group theory method with the necessity of a compact formulation.
