Formation of the State‐Selected CH Radical Beam and its Application to The CH + NO Reaction

Abstract

The CH(X 2 II) radical beam was produced via the decomposition of methanol by a dc‐discharge in a pulsed supersonic beam. The CH radical beam was rotationally state‐selected and separated from other discharge products by using an electrostatic hexapole field. The chemiluminescence from the reaction of CH in the |3/2, 3/2, 3/2> state with NO was measured under the crossed beam condition. The wavelength region of the present chemiluminescence confirms no NH(A 3 II) formation. The formation of HCN(X) and/or OH(X 2 II) is tentatively proposed.
