Abstract Raman, infrared, and 1 H and 13 C NMR spectra of 2-(dimethylamino) ethyl pivalate, 2-(pivaloyloxy) ethyltrimethylammonium iodide, poly [2-(dimethylamino) ethyl methacrylate] and of its quaternary iodide were measured. Spectral analysis revealed that in crystalline 2-(dimethylamino) ethyl pivalate and in its quaternary salt, the 2-(dimethylamino) ethyl group exists in the g conformational state. In the liquid state, these compounds also ...
