Our research program over the past twelve year period has utilized the triplet state of chlorophyll as a (nondestructive) probe into the structural and dynamical nature of the photosynthetic unit. Using primarily zero-field optically detected magnetic resonance spectroscopy, supplemented by resonance raman spectroscopy, we have examined the chlorophyll molecule for a range of environments in both in vivo systems and in model chlorophyll units in vitro. Our research effort has focused on chlorophyll in the presence of simple organic ligands, in lipid bilayer vesicles, in synthetically reconstituted protein, and on the surface of metal and non-metal substrates. Aim of the research was to detail the physical features and interactions of the photosynthetic pigment systems through examination of pigment subunits of the photosynthetic apparatus and model systems which represent them.
