Different Origin

Summary On the basis of the proton NMR relaxation time dependencies on temperature and frequency in cellulose pulp a simple two-motion model of molecular dynamics has been proposed. The parameters, activation energies and correlation times, describing the model may be correlated with structure features such as level of crystallinity of cellulose with different origin, as well as degree of paper devastation.

Clear Relation

Monte Carlo simulations of complex rotation of single −CH3 groups, −(CH3)3 groups and −BH3 groups were performed for trimethylamine borane (CH3)3NBH3. In the course of these simulations the correlation functions for different models of rotation were determined. Knowledge of these functions and of some data extracted from NMR experiments allowed for the calculation of the longitudinal magnetic relaxation time T1 as a function of temperature. The values of relaxation times obtained from Monte Carlo simulations are compared to experimental results published by other authors. There is a clear relation between the assumed model of rotation and the shape of the T1 curve versus temperature.
