    • In VB/MM Hij was approximated by the following equation. Hij, H′QM,ij, w iHiiint, WjHjjint)S′QM,ij, where w i and wj are the weights of Φi and Φj respectively and wi, wj, 1/2 was used only in the special cases in which Hii, Hjj. However, an in depth examination of the effect of using wi, wj, 1/2 instead of the actual respective weights was found to be negligible see Supporting Information, Since using the weights requires several iterations to obtain their correct value, and since there is no clear justification for using the relative weights rather than equal average of the interactions, we decided to use the latter, which is the simpler vers

    • The weights are fixed at this stage because in order to change them one should proceed with a quantum calculation as described in the subsequent steps. Since one step in dynamics is not expected to cause major changes in the weights, and since, within our method, one QM calculation is much more computer demanding than running several dynamics steps, we perform relaxation of the solvent to predetermined weights, then change the weights and repeat the relaxation until convergence is obtained
