✦ Synopsis

Modulation cffccts induced by intcnction of an unpaucd clecuon wrth I4 N nuclc~ of pyrrolc rmgs in the electron spin echo from chlorophylIa radiui ntzons have been invcstigatcd. The moduhtmn frcqucncics have been detcrnrmed by Founer analysis of the echo sgnr11 decay. The modula~ioo frequencies appro~mete to the qu~d~upoIc rw,onancc kqueocm of 14N nuclei 1. introduction
