Abstract

From an analysis of the high-resolution spectrum of the 3ν3 manifold of SF6, we have determined the anharmonicity constants to be (in reciprocal centimeters) X33 = −1.7426, G33 = 0.9188, and T33 = −0.24635. By using these constants, one can for the first time to our knowledge accurately predict the energies of the lower-vibrational sub-levels of the ν3 ladder and determine the pathways for multiple-photon absorption.
