High-resolution emission spectra of VO have been recorded in the region 3400-19400 cm(-1) using a Fourier transform spectrometer. The molecules were observed from the reaction of VOCl3 with active nitrogen. Two new bands, with origins near 5539.46 and 5551.69 cm(-1), are assigned as the 0-0 bands of the (2)Phi(5/2)-(2)Delta(3/2) and (2)Phi(7/2)-(2)Delta(5/2) spin-orbit components (respectively) of a (2)Phi-1(2)Delta electronic transition of VO. A rotational analysis of both subbands has been carried out and spectroscopic constants have been extracted. The 1(2)Delta state is known from the previous analysis of the near infrared doublet transitions of VO and the new (2)Phi excited state has rotational constants very similar to those of another (2)Phi state observed previously [Merer et al., J. Mol. Spectrosc. 125, 465 (1987)]. (C) 2002 Elsevier Science (USA).
