We investigate the nanometrology of sub-nanometre particle sizes in industrially manufactured sodium silicate liquors at high pH using time-resolved fluorescence anisotropy. Rather than the previous approach of using a single dye label, we investigat

The diffusional dynamics of excited polar fluorescent molecules in an external electric field is considered. The time-dependent part of the Stokes shift and the fluorescence anisotropy are determined as functions of time following δ-pulse excitation

This work provides a description of the solvatochromic effect in terms of a hard-sphere model taking into account the microscopic parameters of the solution. The average energies of the solute-solvent system were calculated for Franck-Condon and rela

A two-dimensional model of the dipolar solute-solvent interactions has been developed on the basis of the Fokker-Planck equation. This model is used to describe the time dependence of the interaction energy following the electronic excitation. The re

Excited-state protolytic reactions of 4-methylumbelliferone were studied using pulse and phase fluorometry. A concept of internal convolution which simplifies the data analysis was applied. The fluorescence decay of the excited neutral species was fo
