Microwave Spectrum, Quadrupole Coupling Constants, and Dipole Moment of Carbamyl Fluoride

Abstract

The microwave spectrum of carbamyl fluoride, H₂¹⁴N¹²COF, has been studied. The rotational constants are A = 11 304.39 Mc/sec, B = 11 176.14 Mc/sec, and C = 5616.06 Mc/sec. The quadrupole coupling constants have been determined from the splittings of low‐J transitions. These are eQq_m = −4.05 Mc/sec and η=−0.165. Two components of the dipole moment were determined and are μ_a = 3.33 D and μ_b = 2.31 D. No excited‐state spectrum was observed.
