A spectrofluorometer is described consisting of an excitation source, optics, detector and time resolving electronics. The excitation source consists of a mode-locked Ar ion laser, which synchronously pumps a dye laser, followed by a frequency doubling device. The repetition frequency of the U.V. pulses (FWHM some ps) has been reduced by an extra-cavity electro-optical modulator. Provisions have been made in the optical configuration to determine both time-resolved fluorescence spectra and fluorescence anisotropy decay curves. The commercially available electronics have been optimized for maximum time resolution. The spectral output of the excitation source is confined between 280 and 310 nm, which encompasses the region for eliciting protein fluorescence. The performance of the complete system has been tested with single lifetime standards like p-terphenyl in cyclohexane or with N-acetyl-L-tryptophanamide in pH 7.5 buffer. Serum albumins from human and bovine sources have been employed as examples for time resolved fluorescence spectra and for the demonstration of anisotropy decay curves. Using these methods protein dynamics in the (sub)nanosecond time region can be directly explored.
