Chemical reaction has been observed upon excitation of ketene-NO pairs isolated in an argon matrix at 12 K with 380- and 355-nm laser radiation. The reaction product was identified as the iminoxy radical CH[sub 2]=N-O by FT-IR spectroscopy. The CH[sub 2] group transfer occurs at excitation energies below the lowest dissociation barrier of ketene and constitutes the first example of a photochemical carbenoid reaction. 45 refs., 4 figs., 1 tab.
