Abstract: | Laser Stark measurements have been made on the 02000000 and 03100110 vibrational transitions of 16O12C32S, 16O12C34S, and 18O12C32S, and on the 03100110 transition of 16O13C32S, using a CO2 laser. In addition to providing dipole moment information for excited vibrational states, these measurements give vibrational band centers accurate to several megahertz. To aid in optical pumping experiments, several near coincidences between CO2 laser transitions and OCS absorption lines are discussed. Electric-field-allowed ΔJ = 0 transitions are observed for the 2ν2 band of 16O12C32S and 16O12C34S, as well as ΔJ = 2 transitions for the same band of 18O12C32S. |
