✦ Synopsis

The b 3 S 0 -a 3 P system of BH has been extensively characterized by emission spectroscopy using a CESE source. Vibrational levels up to Β£ Γ… 8 in the b 3 S 0 and Β£ Γ… 7 in the a 3 P state were observed, allowing construction of RKR potential curves covering almost 80% of the well depths. Dissociation energies were estimated from the observed vibrational levels using the near-dissociation extrapolation method. Comparison of the extrapolated curves with theoretical calculations resulted in the following best estimates for the dissociation energies: a 3 PD e Γ… 19 250 cm 01 , b 3 S 0 D e Γ… 20 960 cm 01 . The BH singlet-triplet separation is estimated to be 10 410 cm 01 . The recently observed predissociation of the b 3 S 0 state was too weak to be detected.
