Determination of the gas temperature of a low-pressure plasma from the intensities of the H/sub 2/ and D/sub 2/ molecular bands. 1: Rotational structure of the Fulcher band system

摘要: The literature data and measurements with high resolution emission spectra of a low-pressure arc discharge are analyzed in order to develop method which is used, along the necessary numerical data, determine rotational temperature plasma from relative intensities spectral lines structure diagonal vibronic bands Fulcher system for molecular hydrogen (the transitions 1ssigma3p..pi../sup 3/Pi/sub u/,v'..-->..1ssigma2ssigma/sup 3/..sigma../sup +//sub g/,v'' v'
