Fluorescence spectroscopy and Franck–Condon-factor measurements of low-lying NO Rydberg states

Abstract
Time- and frequency-selective excitation spectroscopy has been demonstrated on electronic transitions from the A, B, C, and D states of the NO molecule and has been used for separating overlapping electronic systems. Using a tunable, narrow-band, coherent VUV source, laser-induced fluorescence from individual rotational vibrational levels of the NO molecule has been measured and is shown to be in good agreement with theory.
