Optical free induction and fluorescence decay experiments on pentacene following narrow band laser excitation are reported. From the results we conclude that pentacene for its lowest 1B2u ← 1A1g transition is a perfect two-level system and from the power saturation term in the OFID we calculate a transition dipole moment of 1.5 ± 0.2 debye. A long-lived transient observed in the fluorescence during the onset of cw dye laser excitation is ascribed to a bottle-neck in the optical pumping cycle.
