英文摘要 | Infrared photodissociation spectroscopy was employed to establish the general trends in the stepwise growth motif of cationic dimethylamine (dma)(n)(+) (n = 4-13) complexes. electronic structure calculations were performed to identify the structure of the low-lying isomers and to assign the observed spectral features. the results showed the preference of the formation of the proton-transferred (ch3)(2)nh2+ ion core. the (ch3)(2)nh2+-[(ch3)(2)n] ion-radical pair contact and the ion-radical separated pair could coexist at n = 4. the [(ch3)(2)n] radical is separated from the (ch3)(2)nh2+ ion core by one dma molecule at n = 4-6 and by two or more dma molecules in the larger clusters. this suggests that the (ch3)(2)nh2+-[(ch3)(2)n] ion-radical contact pair is not stable in the subsequent radiation-induced processes of dma, and the [(ch3)(2)n] radical is released from the charged site in the cationic dma networks. |
