Abstract
The microwave spectrum of ethyl isocyanate, CH3CH2NCO, has been obtained in the frequency region from 8.5 to 35.5 GHz. The spectrum identified is attributed to the cis conformation, in which the methyl group eclipses the isocyanato group. The rotational constants in the ground vibrational state obtained are A=14110±3, B=3067.91±0.02, and C=2605.01±0.02 MHz. The dipole moment (μa) for this rotamer is 2.81±0.02 D. Four sets of vibrational satellites were observed and assigned to the transitions in the first, second, third, and fourth excited states of the C–N torsional vibration.
