NS(B) (Nitrogen Sulfide (B State)) Spectrum Theory and Code

Abstract

During the past year the Laser Kinetics Branch has been studying the B2II - X2II transition in nitrogen-sulfide. We have been particularly interested in this transition because we think the B states 1 micro second lifetime and large Franck-Condon shift make it a good short wavelength chemical laser candidate. As part of our study we have determined the rotational and vibrational populations of the excited molecule produced in an S+N3 to NS(B) + N2 reaction. To do this accurately it was necessary to write a spectrum code. This document outlines the theory, explains how to run, and provides a listing of the spectrum code and accompanying files. It should be noted that even though this code was written specifically for the NS(B2II) - NS(X2II) transition, it is easily modified to do a variety of other molecules and transitions.
