Intramolecular π-π Interactions in Diethanodihydronaphthalene and Derivatives: Dynamic and Static Behavior of the Interactions Elucidated by QTAIM Dual Functional Analysis

Dynamic and static behavior of the intramolecular π–π interactions between ethylene moieties in diethanodihydronaphthalene ( 1 a ) and the derivatives ( 2 a – 12 a ) are elucidated by employing QTAIM‐DFA (QTAIM dual functional analysis), which we proposed recently. Total electron energy densities H b ( r c ) are plotted versus H b ( r c ) – V b ( r c )/2 at bond critical points (BCPs) for the interactions in question in QTAIM‐DFA, where V b ( r...
