Hole bonding, noncovalent interaction

Hydrogen bonding and cr-hole bonding can be treated in terms of the Vs,max and 4s,min on a molecular surface. To deal with noncovalent interactions in general, however, it is necessary to go beyond the qualitative pattern of Vs(r) and its Vs,max and Vs.min, and to fully access the whole range of information that Vs(r) contains. This is done by analyzing it in terms of several statistically defined features, adopted over a period of years as we saw specific needs to be addressed. These features are... 

An Overview of a-Hole Bonding, an Important and Widely-Occurring Noncovalent Interaction... 

The term a-hole bonding refers to an electrostatically-driven, highly-directional noncovalent interaction between a positive region on an atom in one molecule and a negative portion of a second molecule, often a lone pair of a Lewis base. Complexes... 

There have been numerous computational studies of the noncovalent interactions to which we now refer (since 2007 [11]) as a-hole bonding. Only a portion of these will be cited here. Most have dealt with Group VII (halogen bonding) [2, 8, 10, 12, 15, 20, 28, 39-44], some with Group VI [15, 31, 36, 38, 45 17] and a few with Groups V [15, 30, 32, 44] and IV [32, 48],...
