✦ Synopsis

Chemiluminescence of the (a^{3} \Sigma^{+}\left(a_{1}\right) \rightarrow X^{1} \Sigma^{+}\left(X 0^{+}\right))transitions of BiP. BiAs, and BiSb has been observed in the near-infrared spectral region between 6000 and (10000 \mathrm{~cm}^{-1}) from the reactions of microwave-discharged phosphorus, arsenic, and antimony vapor with bismuth vapor in a fastflow system. The spectra consisting of short sequences of red-degraded bands were measured at a resolution of (0.5 \mathrm{~cm}^{-1}) with a Fourier-transform spectrometer. Vibrational analyses of the systems have yielded the following molecular constants of the (\mathrm{XO}^{+})and (a_{1} 1) states of BiP. BiAs, and (\mathrm{Bi}^{121} \mathrm{Sb}) (in (\mathrm{cm}^{1}) ):
