✦ Synopsis

The rotational spectra of ({ }^{79} \mathrm{Br}^{12} \mathrm{C}^{15} \mathrm{~N}) and ({ }^{81} \mathrm{Br}^{12} \mathrm{C}^{15} \mathrm{~N}) in the low-lying (01^{1} 0,10^{\circ} 0,02^{0} 0), and (02^{2} 0) vibrational states have been observed in the millimeter-wave region, and the (v_{3}) fundamental band of both ({ }^{14} \mathrm{~N}) - and ({ }^{15} \mathrm{~N})-containing species has been recorded from 2125 to (2215 \mathrm{~cm}^{-1}) with a diode laser spectrometer. A very precise equilibrium structure has been calculated for cyanogen bromide using the obtained data together with those already known for the normal isotopomers. The ground state rotational spectra of ({ }^{79} \mathrm{Br}^{13} \mathrm{C}^{15} \mathrm{~N}) and ({ }^{81} \mathrm{Br}^{13} \mathrm{C}^{15} \mathrm{~N}) have been also observed, so that (r_{0}, r_{s}), and (r_{m}) structures could be evaluated from the ground state moments of inertia of eight different isotopic species.
