โœฆ Synopsis

The molecular dynamics of thiophene in its neat liquid and in binary solutions with carbon tetrachloride of various mole fractions has been investigated by means of optically heterodyned optical Kerr effect (OHD-OKE) experiment. An unusual increase in orientational relaxation time at the specific mole fraction of thiophene (= 0.7) was observed and it is suggested that the relaxation process is influenced by the complex formation between thiophene and carbon tetrachloride. The concentration dependence of the instantaneous third-order susceptibility is also discussed.

The molecular dynamics of CS2 are investigated in binary liquid solutions with alkane solvents of varying viscosity. The nondiffusive, subpicosecond nuclear responses reveal the influence of many-body effects as they are manifested in the changing local intermolecular potentials on dilution and the

The optical Kerr effect of liquid nitrobenzene and chlorobenzene is probed with 65 fs optical pulses at 633 nm. We observe an instantaneous signal contribution which is attributed to the incoherent (dephased) electronic component of the third-order nonlinear susceptibility x"'. Additionally, three n

Optical anisotropy was created and detected in diluted solutions of all-trans p-carotene in n-dodecane by femtosecond pump and probe pulses. At low pump intensity the anisotropy is due to photoselection produced by one-photon absorption, and it decays with the lifetime (8 ps) of the lowest electroni
