Abstract
The several types of lignin samples (birch, spruce and 'model' lignin) were investigated by laser desorption (LD) Fourier-transform mass spe ctrometry. In the vapor phase under LD conditions, the investigated li gnins prefer to form negative ions of the individual oligomers at well defined mass spacings. Three sequences with Delta m=444 confirm the e xistence of the stable trimer building blocks in the spruce and 'model ' lignin.
