摘要：

A p-polarized visible external reflection spectrum comprised of positive and negative absorption bands was certainly observed as to the protonated tetraphenylporphyrin adsorbed at toluene-aqueous sulfuric acid interface. The results were qualitatively explained that the protonated molecules in J-aggregate could orientate obliquely to the interface.
