摘要：

We obtained high-resolution spectroscopic observations at 2.226 mum of 13 S-type symbiotic binaries using the Phoenix infrared spectrograph on Kitt Peak telescopes. From an empirical calibration we determined v sin i values for the giant components. Combined with information from a program to determine orbits, the rotational velocities have been used to estimate the sizes of these stars and the fraction of their Roche lobes that they fill.
