Abstract

The effect of water on the rotational mobility of molecules in cotton fibres of various kinds has been investigated in some detail by means of ESR spectroscopy of spin labels. Temperature dependences of the correlation time for rotations have been measured, and activation parameters of rotations have been determined for fibres with various degrees of humidity. The method of simulation of theoretical spectra was used to explain the nature of changes in the effective activation energy accompanying increase in the humidity of the fibres. This was accomplished with reference to ideas relating to a heterogeneous distribution of H₂O molecules in the test samples.
