The Photodissociation Threshold of NO2 - Precise Determination of Its Energy and Density-of-States
The NO2 photodissociation threshold has been observed by laser induced fluorescence in a jet at 25 128.57 +/- 0.05 cm(-1). The unexpected high vibronic level density of 2.7 levels/cm(-1) is tentatively attributed to long range interactions between the NO ((2) Pi(1/2)) and O(P-3(2)) products. The energy spacing and intensity distributions indicate rovibronic chaos.
