Homonuclear decoupling for liquid-state NMR
The Journal of Chemical Physics, 2012We present a solution to the problem of decoupling of a homonuclear two-spin system having weak isotropic scalar coupling. We describe non-selective pulse sequences that create an effective field perpendicular to the coupling interaction over a broad range of chemical shifts, with a magnitude proportional to the chemical shifts. Effective decoupling is

Optical detection of liquid-state NMR
Nature, 2006Nuclear magnetic resonance (NMR) in liquids and solids is primarily detected by recording the net dipolar magnetic field outside the spin-polarized sample. But the recorded bulk magnetic field itself provides only limited spatial or structural information about the sample.

Review of advances in coupling electrochemistry and liquid state NMR
Talanta, 2015The coupling of electrochemistry and NMR spectroscopy (EC-NMR) may present an interesting approach in the environmental oxidative degradation or metabolism studies. This review presents experimental advances in the field of EC-NMR and highlights the main advantages and drawbacks of in situ and on line of NMR spectroelectrochemistry. The analysis of NMR

Quantitative 2D liquid‐state NMR
Magnetic Resonance in Chemistry, 2014Two‐dimensional (2D) liquid‐state NMR has a very high potential to simultaneously determine the absolute concentration of small molecules in complex mixtures, thanks to its capacity to separate overlapping resonances. However, it suffers from two main drawbacks that probably explain its relatively late development.

Liquid-State NMR and Scalar Couplings in Microtesla Magnetic Fields
Science, 2002We obtained nuclear magnetic resonance (NMR) spectra of liquids in fields of a few microtesla, using prepolarization in fields of a few millitesla and detection with a dc superconducting quantum interference device (SQUID). Because the sensitivity of the SQUID is frequency independent, we enhanced both signal-to-noise ratio and spectral resolution by ...

Liquid-State NMR of Fluoropolymers
1996The article is a noncomprehensive review of the literature summarizing solution NMR studies of fluoropolymers performed between the 1960 s and 2012. An attempt has been made to describe a representative range of fluoropolymers as well as the NMR methods available to study their structures.

Lipid analysis of Neochloris oleoabundans by liquid state NMR
Biotechnology and Bioengineering, 2010AbstractThis study is an evaluation of liquid state NMR as a tool for analyzing the lipid composition of algal cultures used for biodiesel production. To demonstrate the viability of this approach, 13C NMR was used to analyze the lipid composition of intact cells of the algal species, Neochloris oleoabundans (UTEX #1185). Two cultures were used in this
