The reaction CN+O{sub 2}{r arrow}NCO+O has been investigated in a crossed-molecular beam experiment at a collision energy of 0.76 kcal/mole. Internal state distributions of the ground state NCO({ital {tilde X}} {sup 2}{Pi}{sub 3/2}, 00{sup 1}0,{ital J},{ital e}/{ital f}) products have been measured by laser-induced fluorescence. The rotational excitation is small. There is an observed preference in the population of the {ital K} doublet fine-structure states, 1{ital f}{gt}1{ital e}, and this preference is even stronger for low {ital J} states.
