Abstract
The Ultra violet bands of mercury chloride have been excited in uncondensed discharge and photographed with a quartz Littrow Spectrograph. The Class II system betweenλ 2900 to 2700 suggested by Wieland as due to the triatomic molecule has been studied in detail. In addition to the bands already recorded by previous investigators, a number of new bands has been recorded in the present investigation. A new vibrational analysis of these bands is given. The entire bands are ascribed to the longer wavelength component of2 π-2 ɛ, the other component being the system in the regionλ 2650 to 2400 with a2 π interval of 3335 cm−1 which is in keeping with the corresponding intervals obtained in the case of HgF and Hg I respectively.
The following vibrational constants have been determined.Ν e Ω′ e Ω″ e 36346 cm−1 385 cm−1 292.5 cm−1
