摘要: The dynamics of the photodissociation NO2 into NO(X2ΠΩ″, ν″=0,J″)+O(3P0,1,2) is investigated near thermodynamic threshold. Cooling internal degrees freedom by a supersonic beam expansion provides nearly complete quantum state selection prior to predissociation. Measurements wavelength dependent dissociation yield specific product states are reported. At certain wavelengths Λ″ doublet resolved rotational population distributions fragments obtained. Up an excess energy ofEexc=121 cm−1 about 42% this partitioned rotation NO molecules, and correspondingly 58% translational degree freedom. role electronic total parity discussed.
