Abstract
Measurements of the nascent NO fragments from the photodissociation of gaseous n-butyl nitrite at 266 nm were performed using the one-photon excited laser induced fluorescence technique. The rotational state distributions of the photofragment NO are found to be well characterized by a Gaussian distribution, which indicates that the photolysis process in the S 2 state is a direct and fast dissociation. The measured relative population of NO v″ = 0:1:2:3 is 0.65:0.19:0.11:0.05, respectively. Preferential populations of the NO Π + Λ-doublet state and F 1( 2Π 1/2) spin-orbit state are observed. The TD-DFT calculations of n-butyl nitrite are in good agreement with the experimental results.
