Identification and Analysis of the D' yields A' Transition in the Emission Spectrum of Cl2

摘要

The emission spectrum of chlorine in argon is re-examined using Tesla discharge sources containing isotopically pure chlorine 35 and chlorine 37. Earlier speculation that the dominant emission near 2580 A is due to the D' 2 sub g (3 P sub 2) yields A' 2 sub u(3 pi) transition is confirmed. A weaker band system in the same spectral region is tentatively assigned to beta 1 sub g (3 P sub 2) yields A 1 sub u (3 Pi).
