Blue shifts vs red shifts in sigma-hole bonding

Result description

Abstract sigma-Hole bonding is a noncovalent interaction between a region of positive electrostatic potential on the outer surface of a Group V, VI, or VII covalently-bonded atom (a ?-hole) and a region of negative potential on another molecule, e.g., alone pair of a Lewis base. We have investigated computationally the occurrence of increased vibration frequencies (blue shifts) and bond shortening vs decreased frequencies (red shifts) and bond lengthening for model complexes.

    Modrý posun vs. červený posun ve vazbách obsahujících sigma-potenciálovou díru

  • Czech description

    Vazby obsahující sigma-potenciálovou díru jsou nekovalentní vazebné interakce mezi oblastí s kladným elektrostatickým potenciálem na površích atomů 5., 6. a 7. skupiny, které jsou kovalentně vázány s jiným atomem (tzv. ?-potenciálová díra), a oblastí záporného potenciálu jiné molekuly. Metodami výpočetní chemie jsme vyšetřovali zvýšené vibrační frekvence (modrý posun) a zkrácení vazeb proti sníženým frekvencím (červený posun) a prodloužení vazeb u modelových komlplexů.
