Abstract
The high resolution infrared spectrum of nitromethane with a nearly free methyl internal rotor (V 6 = 2.11 cm −1) has been recorded for the B-type band near 1584 cm −1 with a Fourier transform spectrometer having a resolution of 0.005 cm −1. The ro-vibrational analysis of this dominantly NO 2 asymmetric stretching band has led to the identification of 989 transitions with 0 ≤ J ≤ 42 and 0 ≤ K α ≤ 28 for the methyl rotor m = 0 state. The transitions are fitted using Watson's A-reduction Hamiltonian in the I r representation and the least-squares fit of the assigned transitions yield the centre wavenumber and the effective rotation and centrifugal distortion constants of the upper vibrational state ( v = 1).
