High-resolution Fourier transform spectra of HD80Se in the region of the v1 + v3, 2v2 + v3, 2v1 + v2, 3v1, and v2 + 2v3 absorption bands, with centers located between 4000 and 5500 cm−1, were recorded and rovibrationally analyzed. Energies of the (101), (021), (210), (300), and (012) states, together with those of the formerly reported (010), (100), (020), (001), (120), (110), (030), (011), (200), (002), and (003) states, were jointly used as input information in a "global fit" procedure. This fit provided 161 spectroscopic parameters which reproduce 3323 observed energies with accuracies close to experimental uncertainties. These parameters are compared with those predicted from H2Se. Moreover, experimental band centers for HSeD are compared with those calculated theoretically.
