Self-assembled chlorophyll a and pheophytin a systems in thin solid films have been studied by /sup 252/Cf plasma desorption mass spectrometry (PDMS). The /sup 252/Cf-PDMS spectra of these films show monomer cation and anion molecular ions, ions of molecular aggregates, and positive and negative ion fragmentation patterns arising from the loss of various aliphatic side chains from the chlorin ring. Oligomer ions extending upwards in size to the heptamer were detected in this system.
