Abstract
The spectrum of chlorine excited in the presence of argon has been photographed with a 21-ft. grating spectrograph in the first order. Two band systems in the region 2600-2390 Å and 2365-2239 Å are observed which appear to be respectively analogous to the 2950-2670 Å and 2660-2590 Å systems of bromine reported earlier by Venkateswarlu and Verma. The wavelengths and the wavenumbers of all the bands in the system 2600-2390 Å are given. The vibrational scheme along with the corresponding Franck-Condon parabola is also given. The analysis suggests that the lower state of the system is the 3π (O u +)state established by Elliott at 17658 cm.−1 and that the upper state is at 67773 cm.−1 The vibrational constants obtained arew 0' = 246·6 cm.−1,w 0'x 0' = 0·615 cm.−1,w 0" = 255·2 cm.−1,w 0"x 0" = 5·5 cm.−1,w 0"y 0" = −0·0155 cm.−1 andw 0"z 0" = 0·00115 cm.−1
