Abstract

High resolution spectra of the coupled and degenerate (40+, 0) A1 and (40-, 0) B2 (the local mode pair) states of H2Se are reported. The vibration-rotation transitions of H2 nSe (n = 80, 78) were assigned by using the ground state combination differences and least-squares fits to yield the rotational and coupling constants for the two stretching states with degenerate band origins: v0(40+,0) = 8894·504 cm-1; v0(40-, 0) = 8894·504 cm-1. Several striking local mode limit effects and the formation of fourfold rovibrational energy clusters are observed and discussed.
