Abstract

This paper presents the current effort of detecting trace species nitrogen dioxide (NO₂) by using photofragmentation and Radar REMPI. In this technique, a single near UV laser beam near 381 nm photofragments nitrogen dioxide (NO₂) and resonantly ionize nitric oxide (NO) by means of 2+1 REMPI process. Coherent microwave scattering in-situ measures the total electron number in the laser-induced plasma. The resultant REMPI rotational spectra of NO₂ and NO have distinct difference at 381.794nm which is rotational line and could be due to higher vibrational excitation of NO photo-fragments from NO₂. It provides a method of measuring two species directly which will be helpful for combustion diagnostics and hazardous chemical compounds detection.
