Six-Millimeter Spectra of OCS andN2O

Abstract

The $J=3\mathrm{}\to 4$ pure rotational transition of OCS and the $J=1\mathrm{}\to 2$ transition of ${\mathrm{N}}_2$O have been investigated. The molecules were in their normal isotopic abundances. The results are compared with those of previous investigators. Quadrupole hyperfine structure, $l$-type doubling, and Fermi resonance effects are analyzed.
