    • In the following, we refer primarily to what has been termed "orthodox QTAIM interpretation" [, A. M. Pendas, E. Francisco, M. A. Blanco, C. Gatti, Chem. Eur. J. 2007, 13, 9362 ], as expounded, for example, in, T. A. Keith, R. F. W. Bader, Y. Aray, Int. J. Quantum Chem. 1996, 57, 183. However, it should be noted that broader evolution of QTAIM-type methodology has led to heterodox generalizations that incorporate certain aspects of "orbital decomposition" [, R. Ponec, D. L. Cooper, J. Phys. Chem. 2007, 111, 11294 ], alternative "atoms in molecules" formulations [, A. S. Mitchell, M. A. Spackman, J. Comput. Chem. 2000, 21, 933], or IQA-based extensions to non-equilibrium geometry [Pendas et al.] that might be considered pertinent to the present work (but contain no mention or use of NBO-based methodology as used herein).
