ON THE EXCITATION OF THE EMISSION SPECTRUM OF NCO IN SOLID MATRICES CONDENSED AT 4 °K

Abstract
Seventeen broad (∼50 Å wide) spectral features have been excited in emission between 3000 Å and 4600 Å in the products of a microwave discharge through N2 deposited on a cold (4 °K) surface on which the discharge products of CO + N2 had been previously condensed. The features which lie between 3650 Å and 4470 Å show close agreement with those observed in absorption by Dixon during the flash photolysis of NCO and assigned to the A2Σ − X2Πi transition. It therefore seems likely that the emission features arise from NCO also as a result of the reaction N(2P) + CO(X 1Σ+) → NCO[Formula: see text]at the solid surface.
