Abstract

The conformation of flexible zwitterionic molecules in solutions of polar solvents is studied by means of a NMR chemical shift method. This method makes use of chemical shift changes of NMR lines, induced by the electrostatic field caused by the electrical charges of the zwitterion. The electrostatic field at the observed nucleus is calculated, taking into account the presence of a reaction field due to the polarization of solvent molecules ...
