The polarized excitation spectrum of the triplet-triplet absorption of some hydrocarbons has been measured by the method of photoselection. Advantages offered by the polarized excitation spectrum for further polarization work are briefiy discussed.
PoIarized two-photon fluorescence excitation spectra of indole in hexane, benzimidazole in isopropanoi, and benzimidazole cation in methanol-HaSO.,, all at 0.2 M and 25Β°C are reported for the excitation range 470-600 nm, the region of their L, and L, bands. Relative two-photon absorptivities are ded
Two-photon excited fluorescence excitation spectra using circularly and linearly polarized light are presented for the aromatic amino acids tryptophan, tyrosine (amide form) and phenylalanine in neutral aqueous solution at room temperature. The wavelength range was 440-620 nm, corresponding to 220-3
