A Portable Wideband CMOS NMR Spectrometer for Multinuclear Molecular Fingerprint

Abstract

We present a small wideband CMOS nuclear mag- netic resonance (NMR) spectrometer capable of multinuclear molecular fingerprinting (molecular structure determination). The spectrometer combines a small permanent magnet and a wideband digitally assisted CMOS radio frequency (RF) transceiver integrated circuit (IC) that operates in the RF frequency range from 1 to 100 MHz. This small, thus broadly deployable, NMR system can find applications in online, on-site, or on-demand multinuclear molecular f
