Abstract

Hyperfine structure on the 101 → 000 and 514 → 515 rotational transitions in NH2CHO was measured using a molecular beam maser spectrometer with 8 kHz resolution. The nitrogen quadrupole coupling tensor in the principal inertial axis system was determined. The values are eQqaa = 1960 ± 2 kHz; eQqbb = 1888 ± 3 kHz and eQqcc = -3848 ± 4 kHz. Accurate values for the center frequencies for the rotational transitions were found to be 21 207 432 kHz for the 101 → 000 transition and 23 081 205 kHz for the 514 → 515 transition. One of the nitrogen spin-rotation parameters was also determined: C(514) - C(515) = 1.2 ± 0.6 kHz.
