| Abstract: | Excited radicals CN(A, B), CH(A), H(n=3,4,5) were produced in the energy transfer reaction of metastable He(23S)、 Ar(3P0,2) atoms with C2H3CN molecule by using discharge-flowing afterglow technique. The emission spectra of products were analysed, the results showed that vibrational populations of CN (B, v) were irregular in He(23S)+C2H3CN reaction and the mechanism was that two energy levels of CN(B, v=0,14) were coupled by the other two of CN(A, v=10,30). The relative vibrational population of CN (A, B, v), except the energy level of CN (B, v=14), decreased with the increase quantum number v of vibration which was the statistical population. The nascent rotational temperature Tr of the product CH (A, v=0) was 2600K.The formation mechanism of excited products was suggested as He(23S)+C2H3CN)→CN(A,B)+CH+CH2 →CN(A)+CH2+CN →H(n=1,2,3)+C2H2CN Ar(3P0,2)+C2H3CN→CN(A,B)+C2H3 |
