In vitro determination of the non radiative relaxation time of triplet state in protoporphyrin IX
, 2005 In this work we used Photoacoustic Spectroscopy (PAS) to determine in vitro the non radiative relaxation time (NRRT) of protoporphyrin IX (PpIX) triplet state. In order to obtain this characteristic time, we have used PpIX disodium salt (DS) solutions of
