The nature of the X–H-*-π interactions in X–H-*-π(C6H6) (X = F, Cl, Br, I, HO, MeO, H2N, MeHN and Me2N) was elucidated by applying QTAIM dual functional analysis. The interactions were all classified by pure closed-shell interactions and characterized to have the vdW nature.

The nature of the π-HB and π-EB interactions are elucidated for (EH2)-*-π(C6H6) (E = O, S, Se and Te) with QTAIM-DFA. All the interactions were classified by the pure CS interactions and characterized as the vdW nature, with the suggestion of stronger π-EBs relative to π-HBs.

AIM-DFA (AIM dual functional analysis) is applied to the E–E′ bonds (E, E′ = S and Se) in R-cystine (1), its derivatives and MeEE′Me. The nature of E–E′ is elucidated by (θp, κp: dynamic behavior) and (R, θ: static behavior), through AIM-DFA.
