Asynchronous Fourier transform (FT) Raman spectroscopy with 100 picosecond time resolution has been developed. An additional signal-processing assembly required for time-resolved and transient Raman measurements consists of a picosecond Nd:YLF laser system, a gate circuit, and a low-pass filter. This additional assembly can be attached to any conventional continuous-scan FT-Raman spectrophotometer. The principle of signal-processing employed in this method is almost the same as that of the asynchronous pulsed-laser-excited FT-Raman spectroscopy. This method does not require the synchronization between Raman excitation by probe laser pulses and the sampling by the A/D converter. Transient Raman spectra have been obtained from the first excited singlet state of anthracene in cyclohexane solution and photoexcited poly(p-phenylenevinylene) [(C6H4CH=CH)n] by using 351 nm light (pulse width~70 ps) for photoexcitation and 1053 nm light (pulse width~100 ps) for Raman excitation.
