Suppose I have some classical equations of motion of the form dL/dt = F(L), where L is the angular momentum vector and F is a vector field. Further suppose that F contains a nasty dissipative term. Is there a direct way to get the corresponding quantum mechanical equations of motion? Do I try to go Lagrangian->Hamiltonian->dL/dt = i h_bar [L, H] (i/h_bar? h_bar/i?) I vaguely remember that having a dissipative Hamiltonian does bad things in quantum mechanics. Actually, if somebody could just point me towards a book that would answer these questions, it would be appreciated muchly. Dave
