  RS Ophiuchi is a symbiotic variable and a recurrent nova. We have monitored
it with the Nordic Optical Telescope and obtained 30 high resolution (R=46 000)
optical spectra over one orbital cycle during quiescence. To our knowledge this
is the best-sampled high resolution spectroscopic dataset of RS Oph over one
orbital period. We do not detect any direct signatures of an accretion disc
such as double peaked emission lines, but many line profiles are complex
consisting of superimposed emission and absorption components. We measure the
spin of the red giant and conclude that it is tidally locked to the binary
orbit. We observe Na I absorption features, probably arising from the
circumbinary medium, that has been shaped by previous recurrent nova outbursts.
We do not detect any intrinsic polarisation in the optical wavelengths.
