The aim of the present work was to study a series of peats, leonardites and lignites humic acid samples using different (chemical, 13C isotopic ratio mass spectroscopy, thermal analysis (DTA), infrared Fourier transform and 1H nuclear magnetic resonance spectroscopies) techniques, in order to gain quali-quantitative information on humic substances structure and on the main structural changes that take place during the coalification process.
