Abstract
The microwave spectra of two rotameric forms of methyl hydrazine have been observed and analyzed. By means of the measured rotational constants and electric dipole moments it is possible to make a reasonable assignment of the spectra to the expected “inner” and “outer” unsymmetrical rotamers. Contrary to previous assumptions, the spectroscopic evidence shows the “inner” isomer to be the more stable. The spectrum of each isomer shows prominent inversion doubling. For the more stable isomer the $N^{14}$ hyperfine structure has been analyzed and the barrier to internal rotation of the methyl group has been determined to be $1328 \pm 20 cm^{-1}$.
