Abstract
The UV absorption spectra in solutions in hexane and ethanol of chalcone analogs containing, apart from 2-selenienyl, the following heterocyclic radicals-2-furyl, 2-thienyl, 2-pyrryl, 2- and 3-pyridyl, and 2-quinolyl-have been measured and discussed. Considerations on the electronic influence of the heterocycles have been put forward and the Hammett's parameters have been evaluated for some of the radicals.
