Abstract
The emission bands of diatomic mercury bromide molecule lying in the ultraviolet region have been reinvestigated under moderately high resolution. The bands observed in the wavelength range 2770-2700 AA (previously identified as a new D'-X system) simply form an extension (to high mod Delta v mod values) of the well known C-X system. The vibrational assignment of the bands has been confirmed by measuring the well resolved bromine isotope shift. In some bands structure due to mercury isotopes is also resolved. Precise vibrational constants for the X, C, D and E states and approximate rotational constants for the X, C and D states are reported. The E-X transition is shown to consist of two subsystems indicating that the E state is a 2 Pi state.Keywords
