The interaction between imidazole and tetraphenylporphyriniro;ron(III) in acetone has been studied by following the formation of the bti-imidazole tetraphenyIporphyri&n(Ill) e~mpley at MQ nm. The number of spectraactive species at this waveiength is shown to be two: ~uncomplered tetraphenylporphyrin
