Hunting for 15N DNP in liquids at 14 T

Come see the hunt for 15N enhancement in the liquid state at high magnetic field. Here I show some preliminary data collected this summer during my REU internship at @NationalMagLab.#GlobalnmrOC2024https://t.co/jrizOV2ncE pic.twitter.com/SwIigMBVmJ

15N-DNP has been proven to work up to only 5 T, while other nuclei (13C, 31P) show enhancements up to 14.1 T. Here we show preliminary experiments conducted at 14.1 T on a solution of 15N-aniline doped with BDPA radical and numerical simulation of electron-nuclear hyperfine coupling.
