We present highresolution Xray spectra with the Reflection Grating Spectrometer (RGS) and
mediumresolution Xray spectra and images with the European Photon Imaging Camera (EPIC) of
clusters of galaxies. The RGS has the unique ability to produce highresolution spectra of moderately
extended objects. This has enabled detailed spectroscopy of compact and luminous clusters of galaxies.
We present the first spectra of a selection of clusters that have been observed with the XMMNewton.
Through spatiallyresolved spectroscopy, we constrain the temperature and density structure of the
Xray emitting gas. We make elemental abundance determinations and emission line optical depth
measurements. We relate the measurements to coolingflow models, discuss the dark matter fraction of
