Zusammenfassung:A pressure cell for high resolution spectroscopic experiments at low temperatures is described. The use of helium as pressure medium allows convenient and precise pressure adjustment and assures that minimal strain is experienced by the sample, while the optical access by quartz fibers makes it possible to keep the dimensions of the cell minimal. Hole burning experiments on methyl group tunneling in organic molecular crystals are used to demonstrate potential applications of this cell.
