High-Resolution NMR Spectroscopy with a Portable Single-Sided Sensor

Juan Perlo,1 Vasiliki Demas,2,3,4* Federico Casanova,1 Carlos A. Meriles,5 Jeffrey Reimer,3,4 Alexander Pines,2,4 Bernhard Blümich1*

We report construction of a portable nuclear magnetic resonance sensor with a single-sided open probe design. The resulting magnetic field inhomogeneity is compensated by a pulse sequence that takes advantage of parallel inhomogeneity in the applied radio frequency field. We can thereby acquire fluorine-19 spectra of liquid fluorocarbons with 8 parts per million resolution, surmounting the long-standing obstacle of obtaining chemical shift information with open probe instruments.
