An "improper" form of this phenomenon typically arises only in the presence of weakhyperconjugation, and is characterized by a blue-shifted stretching frequency.
An "improper" form of this phenomenon typically arises only in the presence of weakhyperconjugation, and is characterized by a blue-shifted stretching frequency. In molecularmechanics, this phenomenon is modeled by a 10,12 potential, a variant of the Lennard-Jonespotential. The (*) bifluoride anion exhibits a strong form of this phenomenon as part of a three-centerfour-electron bond. The "i plus k to i" interaction in polypeptides is an example of this phenomenon, andwhen k equals four, corresponds to an alpha helix. For 10 points, name this phenomenon in which anelectronegative atom and a namesake element interact weakly, which explains the high boiling point ofwater.
