Some of the reversible effects of UV radiation on
nucleic acids are hydration of pyrimidine bases and
dimerization of nitrogenous bases pairs.[3] FTIR-ATR
spectra of DNA extract from control and irradiated
kiwifruit samples with different doses are shown in
Fig. 1. Based on literature data,[18–22] the infrared
signals may be assigned to chemical bonds in the following
way: dd (d, in-plane bending d, deoxyribose)
corresponding to 880 cm1,
