## Abstract Indomethacine (**1**) and acemethacine (**2**) contain the substituents ‐OCH~3~, ‐CH~2~COOH, ‐CH~2~COOCH~2~COOH, C‐indole and O‐benzoyl, which are susceptible to protonation in highly acidic media. To determine the protonation sites and the substituent effects reliably, the dissociation

Theoretical calculations at the 3-21G and 3-21+G ab initzo levels and at the MNDO and AM1 semiempirical levels of several six-membered nitrogenated heterocycles and their protonated species have been carried out. The 3-21G calculated proton affinities are systematically too high, in relation to the

The substituent effects on the basicities of 3-, 4-, 5-, 6-, and 7-substituted quinolines were separated into inductive(piai) and pielectronic(prar) components for each position by means of the LSFE equation, whose C

## STO-3C and INDO ulculations on the isomeric cresols and the protouted cresols indicated that protonation occurs most ieadily para to the hydroxy substitucnt, as is observed commonly in experimental work.
