Abstract
The B
2Σ-X
2Σ band system of gaseous barium hydride in the wave length region 8900-11200 Å has been examined in absorption using a King furnace. The spectrum has been obtained by means of Fourier transform spectroscopy. Seven bands have been rotationally analyzed. Term values and molecular constants of the B
2Σ and X
2Σ states have been determined by standard least-squares analysis. The following molecular constants have been derived (cm-1):
