Abstract
A quick spectroscopic method of rotational temperature determination based on the low-resolution emission spectrum of the N2 (v′=2→v″=()) vibronic band profile of the second positive system iras developed. The new method of molecular gas temperature determination was used in an rf glow discharge excited in N2 and N2 + Ar + B2 H6 gas mixture at u pressure range 500–13011 Pa. This method of molecular gas temperature measurement is applicable to nonisothermic plasmas used in plasma-chemical reactors.
