Offset applied; values on the ordinate axis refer to the c spectrum (str. and def. Mean stretching and deformation vibration, respectively).Fig.3.tiff: Enlargement of hydroxyl (left side) and carbonyl (right side) range of difference ATR-FTIR spectra of cannabis oil exposed 48 h under HPK (a), UV-C (b), and LED (c).Fig.4.tiff: Comparison of the FTIR spectra of chitosan (a), chitosan with 10% cannabis oil (b), and cannabis oil alone (c) with the main absorption bands marked.Fig.5a.tiff: FTIR changes induced in chitosan-based film enriched with cannabis oil by exposure to HPK lamp: full spectral range. The green arrows indicate the trend of changes during exposure time up to 48 h. Fig.5b.tiff: FTIR changes induced in chitosan-based film enriched with cannabis oil by exposure to HPK lamp: enlarged carbonyl range. The green arrows indicate the trend of changes during exposure time up to 48 h.Fig.6.tiff: The difference in FTIR spectra of chitosan-based film enriched with cannabis oil after 48 h UV-irradiation under: HPK (a), UV-C (b), and LED (c) lamp.Fig.7a.tab: Changes in the content of methyl/methylene groups in film based on chitosan and enriched with cannabis oil sample after UV-irradiation from three different sources (calculated as relative percent changes in absorbance at 2930 cm−1).
