Bamers to rotation about the partial double C-N' bond were determined from line shape analysis of 'H and I3C dynamic NMR spectra of N',N'-dimethyl-NZ-substituted phenylacetamidines with twelve different substituents on the phenyl ring. The values of AGGc are 51.2-58.7 kJ mol-' and the correlation wi

H NMR studies of the micellization process in N-dodecyl-N,Ndimethyl-N-benzylammonium chloride (DBeAC) were carried out. The spectra were measured at concentrations below and above the critical micelle concentration (CMC). The chemical shifts and Nuclear Overhauser Effect (NOE) measurements were anal

## Abstract ^13^C and ^15^N NMR chemical shifts were measured for __N__^1^โ€alkylโ€__N__^2^โ€arylthioureas. The absence of decoalescence of the __N__^1^โ€alkyl group carbon signals down to 190 K, the europiumโ€induced chemical shifts and the molecular mechanics calculations indicate that the preferred c
