Rotational spectrum , structure , and modeling of the HCCH – „ OCS ... 2 trimer : Observation of a polar OCS dimer fragment

Abstract

The rotational spectra of eight isotopomers of the HCCH–~OCS!2 trimer have been assigned by pulsed nozzle, Fourier-transform microwave spectroscopy. The rotational constants and dipole moment components are consistent with a nonplanar, triangular-twisted structure of C1 symmetry which aligns the three monomer axes approximately 3°–27° away from… (More)
