Centre for the Spectroscopic Investigation of Complex Organic Molecules and Polymers; CSICOMP NMR Facility

University of Toronto, Toronto, Ontario
What the facility does

Spectroscopic characterization of molecular structure and analytical services using solution-state NMR, solid-state NMR and EPR

Area(s) of Expertise

NMR spectroscopy is one of the most powerful and versatile spectroscopic techniques for investigating molecular structures and spans many disciplines, from life sciences to material sciences to chemical syntheses.
The Centre for the Spectroscopic Investigation of Complex Organic Molecules and Polymers (CSICOMP) facility is one of the best-equipped facilities in Canada, with nine available NMR spectrometers from 200 MHz to 700 MHz. Two of the systems have cryogenically cooled probes for highest sensitivity, with one optimized for carbon detection and the other, proton and fluorine detection.
The facility has one EPR X-band spectrometer. EPR is a very sensitive spectroscopic technique that relies on unpaired electrons, such as those in free radicals or high-spin metal complexes, to give important structural information. EPR also has applications in dosimetry, investigating the spoiling of food stuffs, defects in nano materials and radical reaction monitoring.
We are available for consultation, for research support, and collaboration. We do EPR and NMR data collection, processing, and interpretation. For those who prefer to conduct their own measurements, we also train clients on routine and advanced NMR and EPR techniques.
