High-resolution FTIR spectroscopy of the ν8 and Coriolis perturbation allowed ν12 bands of ketenimine

Abstract

High resolution FTIR spectra have been recorded in the region 250–770 cm−1 using synchrotron radiation and over 2000 transitions to the ν8 and ν12 states of the short lived species ketenimine have been assigned. Ground state combination differences combined with published microwave transitions were used to refine the constants for the ground vibrational state. Rotational and centrifugal distortion parameters for the v8 = 1 and v12 = 1 levels were determined by co-fitting transitions, and treating a strong a-axis Coriolis interaction. Selection rules for the observed ν12 transitions indicate that they arise solely from “perturbation allowed” intensity resulting from this Coriolis interaction.
