On the Difficulties and Pitfalls with the Analysis of Solid-State 13C NMR Spectra in Graphitic Materials

Resumo

The difficulties and pitfalls with the interpretation of solid-state ¹³C nuclear magnetic resonance (NMR) spectra in graphitic materials are discussed in detail here, with special emphasis on the case of ¹³C-enriched samples, which have been used in several recent NMR studies. The issues with the spectral simulation and the interpretation of the spectral parameters obtained by some arbitrary models reported in the recent literature are examined and alternative methods to obtain informative experimental data and to analyze them in a more appropriate way are presented.
