摘要：

Optical and ODMR data for dimers of pheophytin a and b and chlorophyll a and b are presented. It is proposed that pheophytin a forms a parallel dimer arising from π-π interaction, binding being essentially different from that in the corresponding chlorophyll dimer. The dimer of phcophytin a is less stable (K ≈ 104 ol/mol) than that of chlorophyll a(K ≈ 106 ol/mol). © 1979.
