概要

For analogous normal vibrations in conjugated systems of a similar type a linear relationship often exists between vibrational frequencies and bond orders. We find that this linearity can, in principle, be extended to include conjugated systems in both excited electronic states and ionic states. This indicates that the linearity covers a full range of bond order conceivable for conjugated systems. Such an aspect of molecular vibrations gives a concise and sometimes decisive clue not only to vibrational assignments but also to structural analyses of conjugated systems in various electronic states. Symmetric C=C stretching vibrations of ethylene and tetracyanoethylene nicely illustrate this situation.
