Abstract

The CH(X²II) 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(A³II) formation. The formation of HCN(X) and/or OH(X²II) is tentatively proposed.
