The potential energy surface of 4-methyl-3-indole acetic acid IAA was investigated via RHFr6-31G\* calculations. Five symmetry-unique local minima with syn-periplanar orientation of the COOH group are present. In contrast, unsubstituted IAA and 4-Cl-IAA have only four such minima. The shape of the e

An ab initio conformational analysis of 4-chloroindole-3-acetic acid was performed at the RHF/6-311G \* \* level. The mirror symmetrical conformer (in which the indole ring is coplanar with the COOH group) is most stable; next in energy are the two conformers with the C-COOH fragment perpendicular t
