Abstract: Damage to paper (sulfate pulp, cotton half-stuff, and flax half-stuff) caused by the Aspergillus niger, A. sclerotiorum, and Penicillium chrysogenum fungi is investigated by Raman spectroscopy, Fourier-transform infrared spectroscopy, and scanning electron microscopy. It is shown that the use of application infrared Fourier-transform absorption spectroscopy allows one to identify the initial stages of damage from a decrease in the degree of crystallinity of the cellulose contained in paper. The absorption band near 900 cm –1 is used as an indicator of early stages of damage. An increase in the amide II peak at 1550 cm –1 and spectral changes in the region of valence vibrations of the C–H bonds (2800–3000 cm –1) are observed in the case of heavier damage. The obtained data indicate that the vibrational spectroscopy techniques are promising in the study of damage of archive documents.
