The rotational Zeeman effect of CH3 -NO2, a molecule with a very low barrier to internal rotation has been studied at field strengths up to 25 kG. From the Zeeman splittings of rotational transitions in excited torsional states the “g-value of the methyl-group” was determined to be ga= +0.347 ± 0.002. This comparatively high value indicates that in nitromethane valence electrons are shifted from the C - H-bond region towards the NO2-group, an explanation which is backed by the results of CNDO/2 and INDO-calculations.
