Abstract

In the present project 1H and 19F Diffusion-Ordered Spectroscopy (DOSY) will be applied with or without surfactant addition to evaluate the effect of surfactant to complex mixture separation, dubbed MAD (Matrix Assisted DOSY). Several molecular systems are chosen to these purposes, where target molecules possess acidic or basic groups and in some cases at least one fluorine atom is present in the studied molecule. Fluorinated compounds were chosen due to special characteristic of fluorine atom from NMR and pharmaceutics point of view. (AU)
