High-overtone Spectra and Dipole Moment Functions for the C–H Stretching Vibration of Chloroform

The absorption spectra of liquid chloroform were observed for the C–H stretching fundamental vibration and its overtones up to v=←50. The spectral parameters were analyzed on the basis of the one-dimensional local mode representation, which led to the determination of the mechanical and electrical anharmonicities. The solvent effects on the absorption intensities are discussed from the viewpoint of the solvent effect on the dipole moment function. The finally obtained dipole moment function was compared with that obtained by the ab initio calculation.
