Photoelectron energy and angular distributions of NO following three different high-order multiphoton ionization (MPI) schemes have been measured. The 3+3 resonantly enhanced multiphoton ionization (REMPI) via the A{sup 2}{Sigma}{sup +} (v=0) level yielded a distribution of electron energies corresponding to all accessible vibrational levels ({ital v}{sup +}=0--6) of the nascent ion. Angular distributions of electrons corresponding to {ital v}{sup +}=0 and {ital v}{sup +}=3 were significantly different. The 3+2 REMPI via the A{sup 2}{Sigma}{sup +} ({ital v}=1) level produced only one low-energy electron peak ({ital v}{sup +}=1). Nonresonant MPI at 532 nm yielded a distribution of electron energies corresponding to both four- and five-photon ionization. Prominent peaks in the five-photon photoelectron spectrum (PES) suggest contributions from near-resonant states at the three-photon level.
