摘要: Abstract Deoxygenation of 6-cyanophenanthridine 5-oxide (6CPNO) in the lowest triplet state was confirmed by sensitization proflavine with visible S 1 ←S 0 absorption band ( λ max =460 nm) ethanol. Absorption bands (6CP) grew up at expense those N -oxide a selective steady-light (>420 nm) irradiation presence -oxide. In 460 nm laser pulse excitation proflavine, furthermore, weak transient due to sensitized detected around 410 nm.
