The near ultraviolet emission spectrum of m-fluorochlorobenzene

Abstract

The emission spectrum of the m-fluorochlorobenzene molecule, obtained by means of a controlled transformer discharge through the flowing vapor of the substance, has been recorded on Zeiss medium quartz spectrograph. It lies in the region 2550-3000 Å with a weak continous background on the short wavelength side and strong background on the longer wavelength side. The vibrational analysis, presented in this paper, assumes four excited state vibrational frequencies 376, 474, 666, and 835 cm-1; eleven ground-state vibrational frequencies 196, 242, 414, 516, 687, 884, 998, 1065, 1139, 1222, and 1426 cm-1 and two difference frequencies 81 and 69 cm-1. © 1967.
