Abstract
The ground-state rotational spectra of five isotopic species of a weakly bound dimer formed by OCS and HCl in the gas phase have been investigated by pulsed-nozzle, Fourier-transform microwave spectroscopy. The observed spectra have been interpreted in terms of a linear (or nearly linear) equilibrium geometry with nuclei in the order SCOHCl and lead on analysis to the following spectroscopic constants: [graphic omitted]. The values of DJ lead to kσ= 1.19 N m–1 for the intermolecular stretching force constant, while the rotational constants B0 give r(OCl)= 3.4787 (1)Å for the species containing protium and r(OCl)= 3.4751 (1)Å for the species containing deuterium.Keywords
