چکیده انگلیسی
Nanosecond time-resolved UV/vis absorption spectroscopy on laser flash photolysis and calculations based on (time-dependent) density functional theory for radical cations of 7-benzhydrylidenebenzonorbornene (3) and 7-benzhydrylidene-2,3-dimethylenenorbornane (4) indicated their contrasting molecular geometry and electronic structures, suggesting the nonclassical and classical nature of 3
- + and 4
- +, respectively, which originated from the different patterns of electronic coupling between the C-7-C-8 and C-2-C-3 subunits.
