Sažetak

The variations in PMR line parameters of taurine
[NH; CH2CH2so; J and E-aminocaproic acid [NH; (CH2)5Coo-1
were studied in a wide temperature region. They were explained
in terms of rotational motion of NH; group. The energy barriers
hindering such a motion were calculated, and they are V 0 = 5.0
kcal mo1e-1 for taurine, and V0 = 9.0 kcal mo1e-1 for E-aminocaproic
acid. The influence of hydrogen bond length N - H . . . O
and position of NH; group in a molecule upon the extent of
hindering, were shown.
