      For a tunneling system we consider the coupling to the    dissipative environment of the coordinate q, the momentum p    and the potential function U(q). In the frame of the   quantum  theory of open systems we derive a quantum master   equation,  fundamental constraints and uncertainty   relations. We obtain  an analytical expression of the   tunneling spectrum and show  that at thermal equilibrium its   shape entirely depends on the  barrier characteristics while   its amplitude is proportional  to the strength of the   dissipative coupling.
