Abstract

Hyperfine structure on J=1→0 transitions in CH₂D ³⁵Cl and CD₃³⁵Cl was observed with a molecular-beam maser spectrometer. Splittings arising from deuteron quadrupole coupling were completely resolved for some transitions and partially resolved in others. The ³⁵Cl quadrupole coupling along the C-Cl bond direction was eq_zzQ = 74 687.3±0.5 kHz for CH₂DCl and eq _zzQ = 74 573.1±0.5 kHz for CD₃Cl. This is a difference of 0.15% for the ³⁵Cl quadrupole coupling in the C-Cl bond direction. The average deuterium quadrupole coupling strength was eq _zzQ= 170.8±6.0 kHz. Calculation of hyperfine structure due to four quadrupole nuclei, three of which are equivalent, is discussed.
