A qtrantum statistical naodel for the relaxation of two strongly cotrpled spin 172 particlestoxvard thertnal eqtrilibritrrn is forrntmlated uauicroscopically tmsing a master equation. Ratnan-typedissipation mechanisuaas are introdtrced in addition to the ustral bilinear cotrpling between tluecotrpled systena and the reservoir. The efl'ects of two different rotating wave approximationsto derive the raaaster eqtration are investigated. Decoherence is considered as a process toxvardthermal eqttilibritrm f'or the dissipative systerau and is sttrdied by observing the phase and energyrelaxation-
