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.
