Demonstration of NV-detected NMR spectroscopy at 8.3 Tesla

ORAL

Abstract

High field nuclear magnetic resonance (NMR) spectroscopy offers high spectral resolution and new insights into the study of complex biomolecules. The nitrogen-vacancy (NV) center, due to its unique properties, has enabled widespread study of nanoscale NMR at low magnetic fields [1]. However, conventional NV-detected NMR based on AC magnetic field sensing is not applicable at high magnetic fields, requiring the development of alternate techniques. Furthermore, there have been few studies of NV-detected NMR at high fields due to the technical challenges involved [2]. Within this work, we explore an NV-detected NMR technique suitable for applications of high field NMR [3]. We demonstrate optically detected magnetic resonance (ODMR) with the NV Larmor frequency of 230 GHz at 8.3 Tesla, corresponding to a proton NMR frequency of 350 MHz. We demonstrate the first measurement of electron-electron double resonance detected NMR (EDNMR) using the NV center and successfully detect 13C nuclear bath spins. The described technique is limited by the longitudinal relaxation time (T1), not the transverse relaxation time (T2). This work demonstrates a clear path to NV-detected NMR at even higher magnetic fields.
