Differences in predictions generated from parameters for the $A\,^3\Pi_1$ and $X\,^1\Sigma^+$ states obtained from some of these studies show that it can be difficult to make reliable predictions outside the data region, especially if one is using conventional Dunham expansions. In the present work, high resolution absorption, 8 (1995).} and laser excitation, 1265 (1994).} data for the $X\,^1\Sigma^+- A\,^3\Pi_1$ system of I$^{79}$Br and I$^{81}$Br, together with earlier microwave, infrared, and fluorescence progression data, are analyzed using a direct-potential-fit (DPF) procedure to obtain accurate analytic potential energy functions for the two states that provide a compact unified description of all of the available data, as well as realistic predictions for the unobserved levels of this species. en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title ACCURATE ANALYTIC POTENTIALS FOR THE $A\,^3\Pi_1$ and $X\,^1\Sigma^+$ STATES OF ${\rm IBr}$ FROM A COMBINED-ISOTOPOLOGUE DIRECT-POTENTIAL-FIT DATA ANALYSIS en_US dc.type Article en_US dc.type Image en_US dc.type Presentation en_US
