Isotope Substitution in near Local Mode Molecules: Bending Overtones nnu2 (n = 2, 3) of the HDS Molecule.

There are two main goals in the present study: (a) to record and analyze the weak overtones nnu2 (n = 2, 3) of the bending fundamental nu2 of the HDS molecule and (b) to derive new isotopic relations for spectroscopic parameters applicable to predict, at least qualitatively, the structures of the excited bending states of HDX-type molecules.
