RASER for Increased Spectral Resolution in Carbon-13 NMR.

ABSTRACT: Precision in nuclear magnetic resonance (NMR) spectroscopy and resolution in magnetic resonance imaging (MRI) are thought to be fundamentally limited by the transverse relaxation time. With the recent advent of radiofrequency amplification by stimulated emission of radiation (RASER), it is becoming apparent that RASERs can break these fundamental limitations and provide significant improvements in the resolution of NMR spectra and the resolution in MRI images. In this article, we show that carbon-13 RASERs can be controlled by changes to the magnetic field homogeneity and the spin coupling network. As illustrative examples of tools commonly employed in high-resolution NMR spectroscopy, we employ the control of magnetic field homogeneity with simple changes to the sample geometry and the sp
