Rovibrational intensities for the Delta V = 1 bands of the X 3Sigma(-) NH radical - Experiment and theory

The vibrational transition dipole moment for the highly reactive radical species NH in its ground electronic state is obtained via the Herman-Wallis effect manifest in emission spectra produced in a plasma reactor. The results of these experiments on the five lowest Delta V = 1 bands are in good agreement with high quality ab initio calculations of the electric dipole moment function.
