Abstract
MICROWAVE studies1,2 of the rotational spectrum of nitromethane, CH3NO2, have been concerned chiefly with the very low internal barrier to rotation. This barrier height has been determined from the microwave spectrum2 by Tannenbaum, Myers and Gwinn as V6=25.2±0.1 J mol−1. Our purpose here is to report quadrupole hyperfine splitting in the microwave spectrum of CH3NO2 caused by coupling of the nitrogen nucleus with the overall rotation.
