Results are reported from visual spectroscopy of the recurrent nova RS Oph, obtained with a Cassegrain spectrograph on the 102-cm reflector at Vainu Bappu Observatory in February-May 1985 (days 32-108 postoutburst). The data are presented in extensive tables and graphs and characterized in detail. It is estimated that the electron density in the ejected envelope decreased from 3 x 10 to the 9th/cu cm on day 32 to 1.8 x 10 to the 8th/cu cm on day 108; the temperature in the coronal line region decreased from 1.5 to 1.1 million K over the same period.
