The room temperature rate constants for the reactions Cl + ClNO and Cl + ClNO/sub 2/ have been measured by the method of laser flash photolysis/resonance fluorescence. The rate constants obtained are (k/sub 2/ +- 2sigma) = (1.65 +- 0.32) x 10/sup -11/ cm/sup 3/ s/sup -1/ and k/sub 4/ = (5.50 +- 0.75) x 10/sup -12/ cm/sup 3/ s/sup -1/. The absorption spectrum of ClNO/sub 2/ was measured in the region 270 to 370 nm and the photodissociation channels ClNO/sub 2/ + hv ..-->.. Cl + NO/sub 2/ and ClNO/sub 2/ + hv ..-->.. ClNO + O were investigated by resonance fluorescence detection of Cl or O atoms. The quantum yields derived are phi/sub Cl/ = 0.93 +- 0.15 and phi/sub 0/ < 0.02.
