Electronic transitions of protonated benzene (Ã (1)B(2)←X̃ (1)A(1), origin at 325 nm) and α-protonated fulvene (Ã (1)A'←X̃ (1)A', at 335 nm) trapped in 6 K neon matrices have been detected. The cations were produced from several different precursors, mass-selected, and co-deposited with neon. After neutralization of the cations, the electronic transitions of cyclohexadienyl (onsets at 549 and 310 nm)
质子化苯 (Ã (1)B(2)←X̃ (1)A(1), 起源于 325 nm) 和 α-质子化富烯 (Ã (1)A'←X̃ (1)A', at 335 nm) 被困在 6 K 氖矩阵中。阳离子由几种不同的前体产生,质量选择,并与氖共沉积。中和阳离子后,环己二烯基(在 549 和 310 nm 开始)和 α-氢化富烯(532 和 326 nm)自由基的电子跃迁被鉴定。在环己二烯基激发到 B̃ (2)B(1) 状态后,观察到光异构化为开链结构和 α-氢化富烯。
