Absorption spectra in the visible and UV regions for tetraphenylporphyrin and its derivatives were determine Their overall protonation constants were obtained. The mols. and mol. units for some tetraphenylporphyrins were calculated by HMO and MNDO methods. The basicities of these compounds are explained.

Key words: ULTRAVIOLET SPECTROPHOTOMETRY, ALKALINITY, SUBSTITUENT GROUP, CORELATIONS, PORPHYRIN, PROTONATION CONSTANT
