Copper complexes of pheophytin, known as copper chlorophyllin (E141), are used in the European Union for a broad range of foodstuff as a water-soluble food … Webthe pheophytin in similar mutants. Density functional calculations were used to calculate the g tensors and rationalize the observed trend in the variation of the g x value for pheophytin and bacteriopheophytin radical. The theoretical results support the experimental obser-vations and demonstrate the sensitivity of g values to
