Abstract
Bitumens isolated from the individual soil horizons of the cambisol sa mples in Boubin-north spruce stand (Sumava Mts.) were analysed using d iffuse-reflectance IR spectroscopy (DRIFTS). DRIFTS is suitable as a s emiquantitative method for the detection of composition changes of soi l bitumens with the increasing soil depth. The aromaticity of soil bit umens decreases, aliphatic chains elongate, and ratio of polar fractio n decreases with the increasing depth.
