ResumoThe nonresonant-two-photon (1+1) zero kinetic energy (ZEKE) photoelectron spectrum out of the 2Π1/2 electronic ground state of nitric oxide is reported. The ZEKE spectra, obtained for different initial temperatures in the jet, show complete rotational resolution of the X 2Σ+ electronic ground state (v+=0) of the ion. Angular momentum transfers up to ΔJ=±7/2 are observed. The rotational J+←J″ branching ratios determined for this ionization process from a valence state differ remarkably from those observed in two-color resonant ZEKE spectra of electronically excited Rydberg states.
