Anisotropy and Energy Disposal in the 193-nm N2O Photodissociation Measured by VUV Laser-Induced Fluorescence of O(1D)

Article abstract of DOI:10.1021/j100130a019

Laser induced fluorescence near 115 nm has been used to measure the Doppler profile of the O(¹D) product of 193-nm N2O photolysis.The anisotropy of product recoil vectors is characterized by the paramter β = 0.50 +/- 0.05.The measured velocity distribution can be used to calculate a distribution of recoil energies that is in reasonable agreement with that reported recently by Felder, Haas, and Huber; an average of 27.3 kcal/mol is deposited into translation, leaving ca. 37 kcal/mol for the internal excitation of the N2 fragment.
