 Title: FOURIER TRANSFORM MICROWAVE SPECTROSCOPIC INVESTIGATION OF CARBONYLSULFIDE LOOSELY BOUND TO TWO HELIUM ATOMS Creators: Xu, Yunjie; Jäger, Wolfgang Issue Date: 2000 Publisher: Ohio State University Abstract: Rotational spectra of the van der Waals complex of carbonylsulfide (OCS) loosely bound to two helium atoms were investigated using a cavity Fourier transform microwave (MW) spectrometer and a MW-MW double resonance spectrometer. Seven isotopomers, namely those with $^{16}O^{12}C^{32}S, ^{16}O^{12}C^{34}S, ^{16}O^{13}C^{32}S, ^{16}O^{12}C^{33}S, ^{18}O^{13}C^{32}S$, and $^{17}O^{13}C^{32}S$ were studied. Nuclear hyperfine structures due to the quadrupolar $^{33}S$ and $^{17}O$ nuclei were observed and analyzed. The interesting dynamics with this cluster will be presented and discussed.
