Abstract
It is shown that the Frohlich bipolaron is feasible in a two-center mo lecular-orbital approach. The binding energy comes out stronger than t he corresponding Heitler-London approach. The critical value eta(c) of eta = epsilon(infinity)/epsilon, below which the bipolaron is realiza ble, is found to be 0.14, which is the best value, otherwise obtained, in the literature.
