Observation of a new electronic state of CO perturbing W¹Π1(v=1)

Heays, Alan; Eidelsberg, M.; Stark, G.; Lemaire, J. L.; Gavilan, L.; Federman, S. R.; Lewis, B. R.; Lyons, J. R.; de Oliveira, N.; Joyeux, D.


We observe photoabsorption of the W(1) ← X(0) band in five carbon monoxide isotopologues with a vacuum-ultraviolet Fourier-transform spectrometer and a synchrotron radiation source. We deduce transition energies, integrated cross sections, and natural linewidths of the observed rotational transitions and find a perturbation affecting these. Following a deperturbation analysis of all five isotopologues, the perturbing state is assigned to the v = 0 level of a previously unobserved (1)Π state...[Show more]
