We derive the tunneling rate for paramagnetic molecules in the context of a
collective spin model. By means of path integral methods an analytical
expression is derived. Given the very large spins in question (s ~ 3000 hbar),
the observation of magnetization changes due to pure unitary tunnel effects is
unlikely.
