Abstract
The orientation and restricted motion of the cholestane spin label (3-spiro-doxyl-5α-cholestane) incorporated into planar multibilayers of diacyldigalactosyldiglycerides extracted from the thylakoid membranes of chloroplasts from different plant leaves has been studied. The experimental ESR spectra were simulated in terms of the slow-tumbling ESR formalism of Freed and co-workers (Polnaszek, C.F.,
