Abstract
The laser Raman scattering signals of a fulvic acid from weathered coal and four humic acids from soils have been observed. The results are similar to those of disordered graphite and the conclusion is supported with X-ray and electron diffraction data. It is found that the Raman signals aren't obviously influenced by the existing forms and states of humic substances and the presence of inorganic minerals. Therefore Raman spectroscopy will become a powerful tool for characterising humic substances in real environment.Keywords
