A very weak interdimer exchange coupling was determined as a function df hydrostatic pressure up to 500 MPa from the EPR line-merging effect. The exchange integral is IJI ~0.0032 cm-t under normal conditions and increases linearly with slope d 1 JI ldp = 6 x IO -6 cm -'/MPa. Comparison between the p
