Vibrational spectra of the isotopic species of nitrosyl halides: A study using the U(4) algebraic model

In this study, I report a successful application of the U(4) algebraic model in the vibrational spectral analysis of the isotopic species of nitrosyl halides. With a detailed spectral analysis, it has been shown in this study that all the isotopic species of NOF, NOCl, NOBr and NOI can be approximated very well using the U(4) algebraic model in its strict local limit.
