Vibrational energy relaxation of the bend fundamental of dilute water in liquid chloroform and d-chloroform

Article Abstract:

The vibrational energy relaxation rates of the water bend in chloroform and d-chloroform are calculated by using the Landau-Teller formula with a new potential model developed and parametrized for describing the chloroform-water interaction. The studies have shown that the relaxation has involved both the bend and the C-Cl stretches and that the frequency changes of all of the modes upon deuteration has contributed to the solvent isotope effect.

Dynamic optical nonlinearities in aniline tetramers

Article Abstract:

Nonlinear optical properties of phenyl/-NH2 end-capped tetraaniline in dimethyl sulfoxide solutions are investigated as a function of the tetraaniline concentration for both doped and undoped samples. Single beam Z-scan technique with 70-ps-duration pulses at 532 nm, are employed in association with others complementary techniques such as UV-vis absorption spectroscopy and time-resolved fluorescence.
