Abstract
An investigation of the internal dynamic of molecular groups existing in a molecule of acid K salt of (E)-2-hydroxyimino-2-cyanoacetic acid ethyl ester is the subject of the work. Using the NMR method we could find such types of motions which could well describe the experimental temperature dependences of spin lattice relaxation time, and the second moment of experimental 1H NMR line. Those techniques of the 1H NMR method allow one to draw conclusions on activation parameters of following motions: reorientation of methyl group, reorientation of ethyl group, H jump in the hydrogen bond bridge, anisotropic (axial) reorientation of the whole molecule around O⋯H–O chemical bonds.
