Notes:
The sensitivity of velocity modulation spectroscopy (VMS) has been greatly improved by use of the frequency modulation enhanced magnetic rotation spectroscopic (FM-MRS) technique. This technique, which we refer to as optical heterodyne magnetic rotation enhanced VMS, has been described in detail in this article, including the experimental configuration, a discussion of line shape, and a systematic analysis of its sensitivity. N2+ 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. © 2001 American Institute of Physics.
