Abstract

A high-resolution Fourier transform spectrum of the D2 MSe species (M = 82, 80, 78, 77, and 76) in the region 2300-2500 cm-1 was recorded for the first time and assigned. On the basis of these experimental data, rotation-vibration energies of the (1 1 0) and (0 1 1) vibrational states were fitted, and band centers, and rotational, centrifugal distortion, and resonance interaction parameters were determined for the main D2 80Se species. The obtained set of 32 fitted parameters reproduces the 647 rotation-vibration energies with a rms deviation of 0.00024 cm-1. The ν1 + ν2 and ν2 + ν3 bands of the other four isotopic species are analyzed as well.
