✦ Synopsis

The carbon K-edge absorption spectra of microcrystalline C,,, have been measured using 270-330 eV synchrotron radiation and compared with that of a previously reported micrccrystalline C,. The differences in the cage structure between the C, and Csa fullercna arc clearly reflected in their XANES (X-ray absorption near-edge structures) features. The Cre cluster contains a significant fraction of sp' hybridized carbon bonds as revealed by the presence of a prominent IF resonance in the XANES spectrum.

The spectra in aqueous solutions were found to remain unchanged at different concentrations, while they were found to differ from those in crystals. These findings suggest that the spectral change does not originate from a long-

## Abstract It is well known that seafood contains high levels of arsenic. For marine animals arsenic is predominantly present as arsenobetaine and related compounds which are not metabolized and are thought to present no toxic hazard to humans. With edible seaweeds, arsenic is present in different
