Abstract: | The 00 band maximum of the transition T3(π, π*) ← T1 (π, π*) of acridine occurs at ≈ 10200 ± 20 cm?1 in inert (n-hexane, benzene, CCl4), at 10220 ± 20 cm?1 in polar (acetonitrile) and at 10170 ± 50 cm?1 in hydrogen-bonding (methanol, 2-propanol and alkaline water) solvents. Based on the solvent-independent energy of T1 (π, π*), the T3(π, π*) state of acridine is estimated at 26050 ± 50 cm?1 in all the solvents. |
