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
