| Because the interconversion of the two tautomers is slower than the actual proton transfer reaction, a conformational change is probably associated with the isomerization. |
| Tautomerism, the existence of two or more chemical compounds that are capable of facile interconversion, in many cases merely exchanging a hydrogen atom between two other atoms, to either of which it forms a covalent bond. |
| Chair-chair interconversion is especially important in substituted derivatives of cyclohexane. |
| Whether the interconversion is considered a chemical or a molecular relaxation process is largely a matter of definition. |
| The proton-neutron interconversion acts to cause a mixing of wave functions and the exchange of a mesonic mediator. |
| This is corroborated by the fact that the interconversion between A 1 and A 3 is very fast at room temperature, which cannot be explained by a simple tautomeric conversion. |
