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
