The microwave and radiofrequency spectrum of H2S⋅Ar

Abstract

Molecular beam electric resonance spectroscopy has been used to determine the radiofrequency and microwave spectrum of H2S⋅Ar, HDS⋅Ar, and D2S⋅Ar. The electric dipole moment and nuclear hyperfine interactions reflect an angular structure in which the H2S C2 axis is nearly perpendicular to the Ar...S axis, and the H2S and argon are nearly coplanar. The effective argon–H2S center-of-mass distance is 3.977 Å.
