High-resolution Fourier transform spectra of HDSe: The interacting states (v1 v2 v3)/(v1±1 v2∓2 v3) with 2v1+v2 = 1, 2, 3, and 4

Abstract

For the first time, high-resolution Fourier transform spectra of HDSe in the region of the three polyads, v₁/2v₂, v₁+v₂/3v₂, and 2v₁/v₁+2v₂/v₂+v₃, have been recorded and analyzed. Combined with an earlier investigation of the v₂ band, and including estimates for the unobserved `dark' 4v₂ band, these levels were subjected to a `Global Fit,' which makes use of relations between parameters within the different polyads. Since there are five isotopic species present in natural HD^MSe (M = 82, 80, 78, 77, 76), altogether 34 vibration-rotation bands have been studied in the present contribution. The parameters determined by the Global Fit reproduce upper vibrational-rotational energies of all these bands with accuracies close to experimental precision.
