Abstract :
A new discharge modulation technique has been applied to color center laser spectroscopy for the detection of radical species generated in a pulsed supersonic jet. Transition in the ν3 band of the CH3 radical rotationally cooled to 23 K were recorded by the phase sensitive detection technique with an improved signal-to-noise ratio. The sensitivity attained corresponds to 6 × 10−5 absorption.
