The sepn. was demonstrated by studying the IR multiphoton dissocn. of CF2DCl [1495-14-3] and CF2HCl/CF2DCl mixts. It is shown how the parameters which control the IR photochem. of CF2DCl such as the temp. and the pressure, as well as the wavelength, the en ...
Absolute diffuse reflectance and transmittance FT-IR spectra of optically thin layers of surface-derivatized silica powders are measured, using a photopyroelectric detector placed in direct contact with the sample. The role of inhomogeneities in the surfac ...
We present cw and pulsed EPR experiments on V4+ in the rutile and anatase phases of TiO2. For the rutile phase, the cw data confirm earlier results, but the relaxation data are different from those previously reported. No earlier results for V4+ in the unr ...
Photoinduced charge transfer processes involving molecules adsorbed at interfaces are a fascinating topic which is presently attracting wide attention. Our investigations have focused on the identification of the factors that control the dynamics of such p ...
An adaptation of Kubelka's general model of diffuse reflectance and diffuse transmittance of light to nonideal scattering samples is proposed. It is applied to quant. Fourier transform IR spectrometry of nondiluted surface-derivatized silica powders. Corre ...
Sub-picosecond transient absorption study has been employed to study the electron transfer kinetics in the dye-sensitized TiO2 films used in commercial photovoltaic devices. The electron injection in these dye sensitized films occurs on an ultrafast time s ...
Porous semiconducting ceramics deposited on a porous metallic film acting both as catalyst and electronic collector gave large photocurrents and considerably enhanced electrooxidation currents when irradiated in the presence of small amounts of alcohol vap ...
