【 摘 要 】

Resonance-enhanced multiphoton ionization with time-of-flight product imaging of the N(²D) atoms has been used to study the N₂O photodissociation at 118.2 nm and the two-photon dissociation at 268.9 nm. These imaging experiments allowed the determination of the total kinetic energy distributions of the NO(X ²�?) and N(²D_5/2) products. The NO(X ²�?) fragments resulting from the photodissociation processes are produced in highly vibrationally excited states. The two-photon photodissociation process yields a broad NO(X ²�?) vibrational energy distribution, while the 118.2 nm dissociation appears to produce a vibrational distribution sharply peaked at NO(X ²�?, �?=14).
