The Far-Infrared Inversion Transition of Vinylamine

The far-infrared spectrum of vinylamine has been recorded and over 1300 transitions between the Coriolis coupled 0 + and 0 − inversion states of vinylamine have been assigned in the region 20-120 cm −1. These have been combined with microwave and millimeter-wave data and fitted to give improved valu...

Description
Summary:The far-infrared spectrum of vinylamine has been recorded and over 1300 transitions between the Coriolis coupled 0 + and 0 − inversion states of vinylamine have been assigned in the region 20-120 cm −1. These have been combined with microwave and millimeter-wave data and fitted to give improved values for the rotational and distortion constants, Coriolis coupling constant (μ yz ) and inversion splitting (Δ E). Five hundred forty-nine b-dipole moment rotational transitions of ( E)-ethanimine have also been assigned in the same spectral region.
