  • Under single-collision conditions,a beam of metastable molecules CO( a,v')generated by DC discharge was allowed to collide with a beam of NO(X)at a fixed angle of 90o . The collision-induced emission from the interaction region was collected at right angles to the beam plane by a lens set and dispersed by a 1 m monochromator where a cooled photomultiplier tube was mounted on the exit slit. The signal from the PMT was transmitted via a discriminator,a photon counter and a boxcar integrator into a computer for storing and processing.

At the collision energy of 0. 05 eV in the present experimental conditions,the electronic energy of CO( a,v' = 0)(6. 01 eV)was not enough to excite NO(X)to NO(b,v' = 4,5)(ΔE > 6. 11 eV). So,what was in act in the energy transfer was the vibrational excitation of CO(a,v' > 0),and the higher the vibrational excitation of CO(a,v') was,the stronger the emission intensity of NO( b-a)could be obtained. It is thought that electron exchange between CO(a)and NO(X)may be operative through the formation of a complex OCNO. The newly discovered formation of NO( b)channel could be well explained considering the energy conservation,spin conservation and electron exchange mechanism.

Abstract: Under single-collision conditions,a beam of metastable molecules CO( a,v')generated by DC discharge was allowed to collide with a beam of NO(X)at a fixed angle of 90o . The collision-induced emission from the interaction region was collected at right angles to the beam plane by a lens set and dispersed by a 1 m monochromator where a cooled photomultiplier tube was mounted on the exit slit. The signal from the PMT was transmitted via a discriminator,a photon counter and a boxcar integrator into a computer for storing and processing. Two broadband emissions were observed around the wavelengths of 780 and 860 nm,which can be assigned to NO(b-a) Ogawa bands Δv = + 4 and + 3 sequences,respectively,and referred to the spectroscopic data given by Huber. At the collision energy of 0. 05 eV in the present experimental conditions,the electronic energy of CO( a,v' = 0)(6. 01 eV)was not enough to excite NO(X)to NO(b,v' = 4,5)(ΔE > 6. 11 eV). So,what was in act in the energy transfer was the vibrational excitation of CO(a,v' > 0),and the higher the vibrational excitation of CO(a,v') was,the stronger the emission intensity of NO( b-a)could be obtained. It is thought that electron exchange between CO(a)and NO(X)may be operative through the formation of a complex OCNO. The newly discovered formation of NO( b)channel could be well explained considering the energy conservation,spin conservation and electron exchange mechanism.
