ANNOTATION
Using a gamma-radiometric method that one of spin bores, the effect of radionuclides on rotational mobility of the formers attached to hydroxyl groups of prickly caper paragons of plants was studied. It has been established that radionuclides contribute to an increase of rotational mobility of spin bores. It is found out that at room temperature in the modified samples there happen retardation of the spin label motions with a correlation time τc ≤ 10с-8 and, in general, the electron paramagnetic resonance specters become narrower, indicating an to increase in the mobility of a nitroxyl fragment. The result of IR-spectroscopy analysis it was revealed that by interaction of the plant with a radionuclide there takes place an alteration of the state of maximums relating to the stripes absorbing valency vacillations of functional groups ОН, СН, СН2 and others. It was found that the energy of intermolecular interactions of hydroxyl groups decreases, as it is evidenced by the shift of the absorption stripes maximum into the plot with low frequency (20–40 cm-1).
KEY WORDS
