IR spectroscopy of the higher fullerene C76-D2 for its qualitative and quantitative determination

Abstract

The higher fullerene C76 of D2 symmetry was isolated from carbon soot by the new and advanced extraction and chromatographic methods and processes. Characterization of the isolated C76-D2 was performed by the FT-IR(KBr) method, over the relevant region from 400 to 2000 cm-1. A series of characteristic dominant and new absorption maxima of this fullerene was registered and confirmed. All the observed infrared bands are in excellent agreement with the theoretical calculations for this molecule. The molar absorptivity ε, as well as the integrated molar absorptivity ψ of its IR absorption bands was determined in adequate and different spectral regions. These results are significant for the qualitative and quantitative determination of the C76-D2 fullerene either in natural resources or in artificially synthesized and bio materials, electronic and optical devices, solar cells, organic field effect transistors, nanophotonic lenses, diagnostic and therapeutic agents, such as for diabetes, pharmaceutical substances, in biomedical engineering and so forth.
