摘要：

Zero-background laser absorption spectroscopy using concentration modulation has been applied to study the near infrared absorption spectrum of the discharge of CH4 and He at a ratio of about 1:170. In the 10300-14250 cm(-1) region, a total of 13 vibronic bands have been observed with 11 of them assigned to the very weak Phillips band system of C-2. Combining these transitions with those observed in emission by Douay et al. [J. Mol. Spectrosc. 131 (1988) 250], a set of spectroscopic constants with high accuracy have been obtained.
