Аннотация

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 HDMSe (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.
