Notes:
A study to observe higher vibrational levels in NCO(A˜ 2Σ+) and the onset of predissociation in this molecule has been carried out. Laser fluorescence spectra have been recorded over the wave number range 27 300–32 900 cm−1, from the A˜(0,0,2)–X˜(0,0,0) band up through the B˜(1,0,0)–X˜(0,0,0) band. Vibrational assignments have been made for a number of newly observed A˜–X˜ bands, and band origin wave numbers and upper level rotational constants have been derived from comparison of experimental spectra with simulations. Decay lifetimes for excitation of a large number of both assigned and unassigned excited vibronic levels have been determined. The onset of predissociation appears to occur at energies slightly below that of the B˜(0,0,0) level. © 1996 American Institute of Physics.
