Abstract
The first high-resolution Fourier transform infrared spectrum of the ν1 fundamental band of the 79Br14N18O isotopic species of nitrosyl bromide located at 1751.29495(2) cmâ1 has been analyzed. Using the Watson-type A-reduced Hamiltonian, the study of the rovibrational transitions has been performed. Rotational constants, quartic and sextic centrifugal distortion terms for the ν1=1 and for the vibrational ground state have been derived. The ground state parameters obtained in this work have been compared to the corresponding constants determined by an empirically refined MRCI (MultiReference Configuration Interaction) force field available in the literature.
