Solid State Nuclear Magnetic Resonance Laboratory
director: J. Koenig

 

Although nuclear magnetic resonance (NMR) has found wide usage for liquids and solutions, it has only been recently that the NMR technique has allowed the study of the solid state.For polymers, NMR in the solid state reveals details of the chemical structure in the state of practical use. Intractable polymeric systems such as crosslinked systems can easily be studied.

Equipment

The NMR laboratory contains a 13C Nicolet Technology NT-150 spectrometer operating at 38 MHz equipped with a cross-polarization accessory. Solid samples are packed into hollow Beams-Andrews rotors for magic angle spinning and can be studied over a considerable temperature range. Chemical shift measurements as well as relaxation measurements can be made. The Bruker MSL 300 MHz instrument in the NMR laboratory has multinuclear capability as well as imaging. This new instrument will also allow the two-dimensional NMR measurements in solids.
