摘要
Emission spectra of the CN(B(2)Sigma+ -X(2)Sigma(+)) and CH(A(2)Delta-X(2)Pi) transitions were observed in the dissociative excitation reaction of CH3CN with the microwave-discharge flow of Ar. The H2O molecules contained in the starting materials and adsorbed on the wall of the apparatus were removed by using P2O5 as a desiccant. The pressure of Ar, P-Ar, was in the range of 0.1-1.0 Torr. The ratio of the concentrations of the CH(A(2)Delta) and CN(B(2)Sigma(+)) states, N-CH(A)/N-CN(B), in the desiccated system was found to be smaller than that in the system without desiccation. The [N]/([N]+[C]) ratio of the a-CNx:H films formed in the desiccated system was predicted to be approximate to0.18, being nearly independent Of P-Ar.
