Multifrequency ESR (1 GHz to 100 GHz) provides an experimental route to study the magnetic interactions in paramagnetic materials. The elucidation of parameters like g, A, D, E, and Q, which characterize these interactions, can lead to an understanding of atomic and molecular structure at magnetic sites. High sensitivity and the ability to investigate small-scale order in powders, polymers, and frozen solutions are key advantages of ESR over a wide frequency range. ESR spectroscopy, combined with techniques such as spin trapping, can be used to detect and follow free radical reactions in biological systems. Our instrument has X-band (8-10 GHz) detector.
Only unpaired electrons will give ESR signals. Please confirm that you samples have/will have unpaired electrons before you submit samples for ESR analysis.
