✦ Synopsis

ZFS parameters for the title chlorophylls in both ordi'nary and fully dcuterated form have been d&mined

under esperimental conditions that auow the aggregation state of rhe chlorophylls to be specified. The triplet state spectra are polarized. The electron spin polarization (ESP) con be analyzed by a simple scheme, and is found to bc sensitive to the agrcgotion state of the chlorophyll. Comparis0.n of in vivo and in vitro bacteriochlorop_hyll spectra supports the chIorophyll special pair proposal fo; the structure of in viva photo-reactive chlorophyll.

We have recorded high-resolution l3C-nmr spectra of collagen fibrils in the solid state by the cross-polarization-magic-angle-spinning (CP-MAS) method and analyzed the spectra with reference to those of collagenlike polypetides. We used two kinds of model polypeptides to obtain reference 13C chemica
