ESR study of complex conformational equilibria in nitroxide biradical solutions

Conclusions

  1. 1.

    The conformational transitions of four nitroxide biradicals in solution have been studied through the effects of temperature changes on the ESR spectra. The solutions in question here can contain as many as five different conformers, each with its own value of the exchange integral.

  2. 2.

    A procedure for analyzing the ESR spectra of biradicals existing in various conformations has been outlined. Thermodynamic parameters have been determined for some of these transitions.
