摘要: Excited state absorption spectra of quinoxaline in benzene, isooctane, and cis‐1,3‐pentadiene at 7 130 ps after excitation are reported. Picosecond kinetics 422 533 nm also In the nonaromatic solvents, bands ∼425 (Sn←S1 Tn←T1) ∼ 530 (mostly Sn←S1) observed transient spectra. Decay ∼530‐nm band gives k−1isc?23 solvents. benzene solvent, excited more complex, decay longer, quinoxaline–benzene exciplex formation is suggested.
