Abstract

Spectra of NGC 6764, a previously unstudied barred spiral galaxy, reveal strong asymmetrical emission lines from the semistellar nucleus. Permitted and forbidden lines are about 750 km per sec wide, which identify the galaxy as a Seyfert galaxy. Spectra in several position angles suggest that discrete gas clouds just outside the nucleus have both tangential and radial components of motion.
