Ground state rotational constants of DM 2Se and HDMSe, M = 76, 77, 78, 80, and 82, have been determined up to octic centrifugal distortion terms from ground state combination differences. These were obtained from rotational analyses of the ν2, ν1, and ν3 bands both of natural and 80Se monoisotopic material recorded with a resolution of ca. 3 × 10-3 cm-1. While the full set of rotational parameters of the 80Se species was determined with significance, some of the centrifugal distortion terms of the less abundant species were either constrained to those of the 80Se species or extrapolated.
