NB686080-26-01894

General Statement of Need The Magnetic Imaging Group (MIG) is requesting a benchtop electron paramagnetic resonance (EPR) spectrometer (also known as electron spin resonance (ESR)) to enhance its capabilities to provide measurements to the magnetic resonance community. This spectrometer would provide new measurements as well as track new species that are not possible in existing nuclear magnetic resonance (NMR) or magnetic resonance imaging (MRI) experiments. This spectrometer would allow for studies of spin species in free radiacal configureations as well as nano-particle composites. At present, the MIG does not have this capability in its group and limits the ability to observe certain species in samples. Electron paramagnetic resonance, also known as electron spin resonance, is a technique that allows for the observation of electrons in configurations such as metals, free-radicals, and as ions in solution. Understanding of spectral position, peak splitting, and g-factor can be very important for understanding the local environment of an electron. This information can be used in further research such as hyperpolarization, material stability, and material sysnthesis. Ongoing research at NIST requires a EPR/ESR system capable of experiments in the X-band range of radiofrequqncy with temperature control, rotational control, and light illumination. The MIG would like to acquire a new benchtop EPR/ESR spectrometer capable of providing these measurements. This project would provide new electron paramagnetic measurements. These additions would bring improved measurement capabilities to the MIG and provide provide flexibility for future work. This project is designed to add a benchtop EPR/ESR spectrometer to the existing suite of magnetic resonance tools owned by MIG. This system will allow for the study of electron spins in radical species, metallic species, nanoparticles, and other various systems. This new capability will enchance the work of our group to the NIST mission of providing quantitative and precise measurements for the magnetic resonance community. In acquiring a benchtop EPR/ESR spectrometer, the MIG will enhance the capabilities of the research group as well as its abilities to study samples as part of its work with the magnetic resonance community. This system will improve the available systems of study as well as stability of solutions containing metal ions. This system will help understand the behavior of electrons in metal films, nanoparticles, and stable radical species.
