dc.description.abstractThe $B \rightarrow X$ spectrum of HgBr is photographed and analyzed for the single isotopic species ${^{200}Hg}^{79}Br$. The analysis confirms Wieland's previous $analysis^{1}$ up to v""=23 but deviates significantly for highest v"". For the higher v"" level presently included in our analysis $(v""=34, {G_{v}}^{""}=4850 cm^{-1})$, the vibrational level spacings do not conform to the theoretical long-range limiting behaviour. However, as a rough upper bounds on ${\Phi_{e}}^{""}$ we obtain the value $5500 cm^{-1}$, which is $500 cm^{-1}$ lower than estimated previously using long-range $theory,^{2}$ Frank - Condon calculations indicate that ${R_{e}}^{""}-{R_{e}}^{""}=0.57 \AA$, which is greater than concluded in earlier $work,^{3}$ Preliminary results of a rotational analysis yield ${R_{e}}^{'}\approx 3.07 \AA$. The $reported^{4}$ HgBr laser lines appear not to coincide with specific band heads in the spectrum. Instead they probably involve a semicontinuous overlap of rotational lines in several v'-v"" bands of the 12 isotopic HgBr molecules of significance in ``natural'' HgBr.en_US
