The High-Resolution FTIR Far-Infrared Spectrum of Vinylamine.
The infrared spectrum of vinylamine, generated by pyrolysis of cyclobutylamine, has been investigated at low and high resolution. The rovibrational structure of the far infrared spectrum (0.002 cm(-1)) has been analyzed, and effective rotational and centrifugal distortion constants have been derived for eight vibration-rotation bands in the region 250-750 cm(-1). The rovibrational structure of two further bands has been assigned using combination differences, and some conclusions have been drawn about the vibrational energy levels involved. With the large amount of new data it is possible to achieve a vibrational analysis of the far infrared region, but not to totally exclude an alternative assignment. Copyright 1999 Academic Press.
