 Title: THE A $^{3}\Pi-X^{1}\Sigma^{+}$ TRANSITION OF ALUMINUM MONOBROMIDE REVISITED Creators: Fleming, P. E.; Mathews, C. W. Issue Date: 1994 Publisher: Ohio State University Abstract: The two most recent $reports^{1,2}$ of the $A^{1}\Pi-X^{1}\Sigma^{+}$ transition of AlBr show remarkable agreement in many of the measured line positions. Nevertheless, there are some significant differences in some of the derived constants. The present paper addresses some of these differences. The spectrum has been recorded in emission in the region 2700 - 2800 {\AA} using a Bruker IFS 120 HR Fourier transfrom spectrometer at a resolution of $0.03 cm^{-1}$. These results permit comparison to photographic data while allowing for the numerous advantages of digital data collections common to Fourier transform spectroscopy. The results are in good agreement with previously reports for the 0-0 hand. The 1-1 band, on the other hand, demonstrates some of the discrepancies previously noted. Results will also be presented on further refinements of assignments for other bands in the system. Description: 1. W. B. Griffith and C. W. Mathews, J. Molec. Spectrosc 104, 347-352 (1984) 2. H.
