Schematic drawing of the setup showing only the section with sub-nanosecond excitation.
Timing of the experiment. The two colors correspond to two laser shots with different delay settings.
(a) Transient absorption of the triplet state of dibromoanthracene in acetonitrile, (b) kinetics at the maximum of the band at 425 nm.
(a) Transient absorption of the singlet and triplet states of anthracene in acetonitrile, (b) kinetics at the maximum of the singlet excited state absorption at 400 nm around time zero.
Transient absorption of pyrene with 5 mM dimethylaniline in acetonitrile. The lower part has been measured using femtosecond excitation, the upper using sub-nanosecond excitation.
Magnetic field effect on pyrene with 0.8 mM dimethylaniline in acetonitrile, difference of transient absorption with and without magnetic field.
