✦ Synopsis

An cleclron spin echo envelope modulahon lrequency analysis is performed ol the 14N and 15N bacleriochlorophyll a* canon in sohd solution Hyperfine couphngs of 2 0 and 3.1 MHz arc derived which correspond to the perpendicular component ol Lhe axial hyperfine coupling tensor. Seven quadrupole lrequencies were measured. six of which group in IWO 5el~ or three zero-lield quadrupole splruings
