Abstract
We report here new Ca II H and K emission line fluxes and equivalent widths for seven RSCVn binary systems, observed at several orbital phases. All the stars show enhanced chromospheric activity. With information from available spectra, an in dividual study for each star has been done. Double emission has been found for some systems in which perhaps the hotter component could be the more active. We have tested spectroscopically the model of localized active regions for the prototype RSCVn.
