Popis:	The fluorescent probe molecule – laurdan (6-dodekanoil-2-dimetilamin naphthalene) – is investigated by experimental and quantum-chemical methods. The influence of the structure non-rigidity on the dipole moments, arrangement of energy levels, and distribution of charges in the laurdan molecule is studied. An optimized structure is obtained and analyzed by the molecular dynamics method. Several structures with different rotation angles of the dimethylamino group are investigated, for which energy, oscillator forces, and nature of electron states are calculated. Fluorescence spectra of the laurdan molecule in an inert solvent are interpreted. Centers of possible interaction of the molecule with a proton-donor solvent are established. Rate constants of radiative and nonradiative processes and quantum fluorescence yields of the examined probe are calculated.
