Marked frequency dependence of the quantum efficiency for hole formation was observed at 4 and 20 K for photochemical hole-burning of free-base tetraphenylporphin (TPP) and sulfonated TPP in poly(viny1 alcohol) (PVA) and other polymers as well as non-photochemical hole-burning of methylene blue in P

We studied the photoinduced electron transfer process at low temperatures by using persistent spectral hole burning spectroscopy. The efficiency of non-photochemical hole burning for zinc tetraphenylporphine (ZnTPP) and zinc phthalocyanine decreased in the presence of electron acceptors. This is att
