Abstract
Modulation effects induced by interaction of an unpaired electron with 14N nuclei of pyrrole rings in the electron spin echo from chlorophyll a radical cations have been investigated. The modulation frequencies have been determined by Fourier analysis of the echo signal decay. The modulation frequencies approximate to the quadrupole resonance frequencies of 14N nuclei.
