Abstract
An electric-resonance optothermal spectrometer has been used to perform microwave-microwave double-resonance measurements on the less stable conformer of methyl vinyl ether. The measured rotational constants are consistent with a gauche structure. The dipole moment components for this conformer have been measured using the Autler-Townes splitting of states that occurs in the presence of a strong, resonant microwave field. Rotational constants, dipole moments and the threefold barrier to internal rotation. $V_{3}$, will be reported. We have searched in double-resonance for the second lunneling component for the equivalent gauche conformer but have found no transitions. This suggests the tunneling gap is larger than about 2GHz.
