MICROWAVE FOURIER TRANSFORM SPECTRUM OF WATER-CARBONYL SULFIDE COMPLEX
Publisher:
Ohio State UniversityAbstract:
Microwave Fourier transform spectrum of the $H_{2}O-OCS$ complex has been observed for the first time. In addition to the normal isotope form, we have also assigned the spectrum of five isotopomers consisting of the $H_{2}O, HDO, D_{1}O, O^{11}CS$, and $OC^{14}S$. The dipole moment of $H_{2}O-OCS$ was determined by the Stark effect measurements of J=2-1 transitions. The most probable structure of $H_{1}O-OCS$ is $C_{1}$, planar with carbonyl sulfide sulfur bonded to the oxygen of the water. The structural parameters of $H_{2}O-OCS$ was found to be very close to those of $H_{2},O-CS1$. These structures are unusual because the structure of isoelectric molecule, $H_{1}O-CO_{2}^{1}$ is known to be T-shaped with an O-C van der Waals bond.
