Emission spectra of the noble-gas halides: the B12A12 system

The B$\text{1}\text{2}$—A$\text{1}\text{2}$ transition has been detected in the emission spectra of ArBr, KrBr, Krl and XeI at low pressure. Comparison with the well-known /ldB–X” continua implies that, in many cases, the latter is heavily overlapped by C$\text{3}\text{2}$—A$\text{3}\text{2}$ emission.
