The far-infrared spectrum of formamide (HCONH2) has been recorded at high resolution and over 9000 vibration-rotation lines assigned. Molecular parameters from the rovibrational analyses of the unperturbed 12(1)0 out-of-plane vibration band have been obtained for the ground state and the excited sta

โฆ Synopsis
molecular beam maser spectrometer with 8 kHz resolution. The nitrogen quadrupole coupling tensot in the principal inertial axis system was determined. The values are eQq,, = 1960 + 2 kHz; @qbb = 188g r 3 kHz and e&cc = -3848 2 4 kHz. Accurate values for the center frequencies for the rotational transitions were found to be 21 207 432 kHz for the ler + Occ transition and 23 081 205 kHz for the 514 * 5rs transition. One of the nitrogen spin-rotation parameters was also determined: WIG) -C(Sts) = 1.2 c 0.6 kHz.
