Abstract

The J=1→0 transition frequencies in CH₃CCD and CD ₃CCH were measured using a beam maser spectrometer. Hyperfine structure from deuterium quadrupole coupling was well resolved. The measured deuterium quadrupole coupling tensor components along the symmetry axis are eQq_aa=228±2 kHz for CH₃CCD and eQq _aa=-55.0±0.5 kHz for CD₃CCH. The coupling strength along the bond direction for CD₃CCH is eQq_zz=174±6 kHz. These results are compared with the other deuterium quadrupole coupling values. Measured rotational constants are B=7 778 170±1 kHz for CH ₃CCD and B=7 355 767±1 kHz for CD₃CCH.
