konformerina

Konformerina is a hypothetical molecular conformation that has not been experimentally observed or theoretically predicted to be stable. The term suggests a structure that is assumed to exist for the purpose of discussion or as part of a thought experiment, often in contrast to a known or more plausible arrangement of atoms in a molecule. The concept of a konformerina might arise in discussions about reaction mechanisms, stereochemistry, or the limitations of molecular modeling. It highlights the dynamic nature of molecules and the possibility of transient, unstable arrangements of atoms. While real molecules exhibit a vast number of possible conformations, only those within an energy minimum are typically considered stable and observable. A konformerina would lie on an energy surface but not at a low point, meaning it would rapidly transition to a more stable conformation if it were to form. The term serves as a useful linguistic tool to describe hypothetical or improbable structures without implying their existence.
