Abstract

The sensitivity of velocity modulation spectroscopy (VMS) has been greatlyimproved by use of the frequency modulation enhanced magnetic rotation spectroscopic (FM-MRS) technique. This technique, which we refer to as opticalheterodyne magnetic rotation enhanced VMS, has been described in detail inthis article, including the experimental configuration, a discussion of line shape, and a systematic analysis of its sensitivity. N-2(+) has been used as a test sample of the technique, and the observed absorption spectrum of H2O+ in the visible region of 16 680-17 300 cm(-1) further confirmed the significant improvement of the sensitivity by this VMS technique.
