Summary

1. The ultrasonic lignin fromPinus sylvestris is bimodal with its main fraction being of low molecular weight (mol. wt. 1600).

2. On mass spectrometry, far-reaching decomposition of the complex lignin molecule takes place under the action of electron impact and thermal decomposition.

3. The structure of the monomeric ions confirms the guaiacyl nature of the USL.
