The violet emission spectra of CN(B<SUP>2</SUP>∑−X<SUP>2</SUP>∑), <I>Δv</I>=0, were observed by the photodissociation of BrCN by Lyman-α radiation (121.6 nm). The peak intensities for the vibrational levels <I>v</I>′≥1 relative to <I>v</I>′=0 decreased with the BrCN pressure (up to 2 Torr), whereas at 0.1 Torr or lower the spectrum was essentially independent of the pressure. The relative vibrational populations (<I>v</I>′=0–10) and the effective rotational temperatures were estimated by a band-envelope analysis. The effective rotational temperature, estimated to be 2000±200 K for <I>v</I>′=0–4, was practically independent of the pressure. Within the low-pressure limit the distributions of the excess energy to vibration and rotation were estimated to be 0.50±0.08 and 0.17±0.02 eV, respectively.
