Photodissociation of methylnitrite in the vacuum ultraviolet. I. Identification and quantum yields of electronically excited NO products

Article abstract of DOI:10.1063/1.440229

The fluorescence of the photofragments resulting from vacuum ultraviolet photodissociation of methyl nitrite (CH3ONO) in the gas phase has been studied using synchrotron radiation from Orsay Electron Storage Ring (ACO) as the source of excitation.In the spectral region between 1100 and 1600 Angstroem where CH3ONO shows a diffuse absorption spectrum, the formation of NO in A²Σ⁺ (v'=0,1,2), C²Π and D²Σ⁺ has been identified by time and energy-resolved spectra.The quantum yields of the photodissociation channels leading to the NO (A,C,D) states have been determined by com parison of the emission intensity with that of pure NO directly excited in A²Σ⁺, C²Π, v'=0, D²Σ⁺, v'=0: φ(CH3ONO->NO A)=0.18+/-0.03 at λ_exc=1440 Angstroem; φ(CH3ONO->NO C, v'=0)=0.07+/-0.02 at λ_exc=1380 Angstroem; and φ(CH3ONO->NO D, v'=0)=0.05+/-0.02 at λ_exc=1200 Angstroem.
