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 eQq_aa = 1960 ± 2 kHz; eQq_bb = 1888 ± 3 kHz and eQq_cc = -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.
