Abstract

The 3p π u c Πu1 -X g+1 (2,0) Rydberg and b′ u+1 -X g+1 (7,0) valence transitions of N214, N14 N15, and N215 are studied using laser-based 1 extreme ultraviolet (XUV) + 1′ UV two-photon-ionization spectroscopy, supplemented by synchrotron-based photoabsorption measurements in the case of N214. For each isotopomer, effective rotational interactions between the c (v=2) and b′ (v=7) levels are found to cause strong -doubling in c (v=2) and dramatic PR -branch intensity anomalies in the b′ -X (7,0) band due to the effects of quantum interference. Local perturbations in energy and predissociation line width for the c (v=2) Rydberg level are observed and attributed to a spin-orbit interaction with the crossing, short-lived C Πu3 (v=17) valence level. © 2008 American Institute of Physics.
