Abstract
The rotational spectrum of the pre-reactive complex thiirane-ClF was detected with a fast-mixing nozzle in an FT microwave spectrometer. Rotational constants, centrifugal distortion constants, Cl-nuclear quadrupole and spin-rotation coupling constants were determined for the isotopomers (CH 2) 2S… 35ClF and (CH 2) 2S… 37ClF. The complex has C s symmetry, with a nearly collinear arrangement of the S…ClF nuclei ( σ≈3.5°) and the ClF axis making an angle φ=95° with the C 2 axis of thiirane. The Cl-nuclear quadrupole coupling constant χ zz along the ClF internuclear axis suggests a significant contribution of the ionic structure [(CH 2) 2SCl] +…F − to a valence-bond description of the complex.
