Noncovalent Interactions

Weak chemical interactions such are hydrogen and halogen bonds are of utmost importance in biochemistry and supramolecular chemistry. They have a very interesting nature, which involves beside electrostatic interactions also repulsive and attractive orbital interactions. Students will investigate the nature of these interactions by decomposition of the interaction energy, by setting-up molecular orbital diagrams and by evaluating the electronic density rearrangements. Phenomena such as cooperativity and resonance-assisted can be understood. Besides the well-known, hydrogen and halogen bonding also other noncovalent interactions are investigated by these methods such as: metallophilic interactions, chalcogen bonding, pnictogen bonding, and (coinage, main-group, ...) metal bonding to name a few.
