I may be getting your question wrong, but it is more appropriate to
apply explicit-electron-treating methods to assess instantaneous
polarizability. With a polarizable model, you can rather "extract" the
pre-parametrized polarizability. I also do not understand the
connection between g_hbond and polarizability.
