Abstract: The hydrogen-bonded complexes formed by indole and coumarin were investigated by varying concentrations. The association constant was calculated from Benesi-Hildebrand equation. Our results show that a 1:1 complex was formed between NH group of indole and the carbonyl group of coumarin. Free energy change of the 1:1 complex was also determined
