Abstract

High-resolution measurements of hyperfine structure on the J = 1 → 0 transitions in CH335Cl and CH337Cl were made using a molecular beam maser spectrometer. The measured 35Cl quadrupole coupling strength is eq Q = 74,753 ± 2 kHz and spin-rotation constant C(35Cl) = 2.4 ± 0.6 kHz. The measured 37Cl quadrupole coupling strength is eq Q = 58,910 ± 2 kHz and spin-rotation constant C(37Cl) = 1.4 ± 0.6 kHz. These results are compared with 35Cl quadrupole coupling strengths obtained for CD3Cl and CD3Cl and a systematic decrease in 35Cl quadrupole coupling is related to changes in the structure and properties of the methyl group on deuterium substitution.
