Safranine in its ground state in the pH range from 2.5 to 6.0 is largely present in its monoprotonated form. Laser excitation followed by intersystem crossing leads to the triplet state. In the triplet state, the favorable species is the diprotonated form in this pH range. The rate constants for pro

The photophysical (visible and fluorescence) behaviour of the dye safranine T has been studied in several polar and non-polar solvents and in micelIar solution (non-ionic and ionic surfactants). The change in the dipole moment of the dye between the ground and excited states has been estimated using
