High-resolution Fourier transform spectra of the D2MSe with M = 76, 77, 78, 80, and 82 in the regions of the first and second bending overtones 2v2 and 3v2 near 1480 and 2210 cm−1, respectively, were recorded for the first time and assigned. On the basis of these experimental data, rotation-vibration energies were determined and fitted together with those of the (010) state reported earlier (W. Jerembeck, H. Bürger, J.-M. Flaud, and Ph. Arcas, J. Mol. Spectrosc. 197, 215-221 (1999)) by using the "Global Fit" procedure. The obtained set of 43 fitted parameters for these three vibrational states of the D280Se species (altogether 86 fitted parameters for 12 states of five M species) reproduces the rotation-vibration energies of all studied states with accuracies close to experimental uncertainties.
