Gas phase vibrational fundamentals and vib-rotational parameters of AsCl 3

Abstract

Contour simulation of the gas phase infrared fundamental bands of AsCl 3 led to estimated values for the first-order Coriolis constants, the vibrational frequencies, and the relative values of the vibrational transition moments. Improved values of the six independent force constants of a general quadratic force field were determined on the basis of the observed frequencies, mean amplitudes of vibration, and Coriolis and centrifugal distortion constants. The potential energy distribution over the normal modes is reported.
