Abstract | High resolution laser spectrum of scandium monobromide (ScBr) between 787 and 845 nm has been investigated using the technique
of laser vaporization/reaction with free jet expansion and laser induced fluorescence spectroscopy. ScBr was produced by reacting laser
vaporized Sc atoms with ethyl bromide (C2H5Br). Spectra of six vibrational bands of both Sc79Br and Sc81Br isotopomers of the C1Σ
+
- X1Σ
+ transition and seven vibrational bands of the e3∆ - a3∆ transition were obtained and analyzed. Least-squares fit of the measured
line positions for the singlet transitions yielded accurate molecular constants for the v = 0 3 levels of the C1Σ
+ state and the v = 0 2
levels of the X1Σ
+ state. Similar least-squares fit for the triplet transitions yielded molecular constants for the v = 0 2 levels of both
e
3∆ and a3∆ states. The equilibrium bond length, r0, of the a3∆ state has been determined to be 2.4789 A˚ .
