It is, perhaps, an appropriate time to remind the reader that we do not, on a general principle, recommend using simplistic MLR-based models such as above for practical investigations of PL systems. What we did mean to demonstrate is that some particular static molecular structures, described using nonempirical electronic structure methods, clearly possess enough information for modeling biochemically-significant PL interactions. We can only hope that this basic insight will, eventually, be combined with more elaborate and robust modeling techniques. As a side note, we would like to mention that our above results, methodological considerations and assumptions may be of interest for several additional reasons (which had not been discussed in preceding sections): [a] physical meaning of LED contributions is different than that of "realistic" NCIs -which do not necessarily exhibit a well-defined dependence on the intermolecular distance; in addition, the relationship between such calculated components and the total binding energy is nontrivial; [b] using and validating MLR models for confirming the very informativeness of predictive variables is a fundamentally different task than establishing statistically-robust models for practical applications -although the two may easily be confused. Thus, we hereby encourage the reader to browse through Appendix B, where such matters are discussed in appropriate length.
