An Investigation of NO Rotational Distribution produced by Photodissociation of Cyclopentadienylnitrosylnickel using Resonance-Enhanced Multi-Photon Excitation for Photoionization

Abstract

The NO radical produced from photodissociation of cyclopentadienylnitrosylnickel was studied using ion-imaging time-of-flight mass spectrometry. Photodissociation of cyclopentadienylnitrosylnickel occurred at 450 nm producing the NO radical. Photoexcitation of the NO productoccurredat 225 nm and subsequent photoionization at 308 nm. There is low correlation between velocity and angular momentum, suggesting that the Ni-NO bond does not bend prior to dissociation.
