Abstract

Hyperfine structure on the 220 → 313 rotational transition of CD2F2 was measured using a molecular beam maser spectrometer with 6 kHz linewidth (f.w.h.m.). The measured deuterium quadrupole coupling strength along the CD bond direction is eqzzQ = 186 ± 10 kHz. The best fit asymmetry parameter is η = -0.15 ± 0.05. Spin-rotation interaction strengths obtained from the spectrum are related to similar terms for CH2F2. The center frequency for the observed transition is 22 727 863 ± 2 kHz.
