A picosecond infrared spectrometer covering nearly the whole fingerprint region has been constructed. The infrared absorption spectrum of electronically excited (S~ state) 4-dimethylamino-4'-nitrostilbene, which is considered to have an intramolecular charge-transfer character, has been recorded. Th

The intramolecular charge-transfer (ICT) process of 4-dimethylamino-4 -nitrostilbene (DNS) in solution was studied by pump-probe and transient CARS experiments with a 1 ps time resolution. Whereas pump-probe experiments give good evidence for the formation of an ICT state in polar solvents, CARS exp
The picosecond transient Raman spectra of S 1 trans-4,4 -diphenylstilbene (DPS) in benzene and toluene at an excitation wavelength of 310 nm and probe wavelengths of 630 and 660 nm are presented. No significant dynamic variations between benzene and toluene in the change in peak position of vibratio
The femtosecond dynamics of 4-(N,N-dimethylamino)-4'-cyanostilbene (DCS) in acetonitrile and methanol solvent was studied by fluorescence upconversion and pump-probe absorption spectroscopy. The spectral evolution observed provides strong evidence for a fast internal charge-transfer (CT) process dom
