The temperature dependence of the 13C nuclear magnetic resonance spectra of porphyrins |
|
| Authors: | David N. Lincoln Victor Wray |
| Abstract: | The high temperature 13C NMR spectra of the methyl esters of deuteroporphyrin-IX and protoporphyrin-IX, and octaethylporphyrin show sharp discrete signals for the inner macrocycle carbon resonances. The temperature dependence of these shifts is discussed. |
