What to expect: Chemical Shifts & Coupling Constants in Low-field NMR Spectroscopy

One of the questions that we always get at tradeshows and conferences is how our instrument compares to high-field data. There are significant inherent differences between low-field and high-field instruments, but the most important from a chemistry point of view are sensitivity (S/N) and resonance dispersion (signal separation).

A bright application…

BODIPY dyes, which are boron difluoride compounds supported by dipyrrinato ligands, have gained recognition as being one of the more versatile fluorophores due to their superior photophysical properties.[1,2] BODIPY derivatives are used as stable functional dyes in several fields such as light harvesters, laser dyes, fluorescent switches, and biomolecular labels.[3-6] They gained popularity as biological probes due to the easy modification of the ligand framework, extension of the chromophore, and substitution of the fluorine atoms.6 Figure 1 shows some commercially available BODIPY dyes used as biological probes.

Life is sweet….maybe too sweet!

Sugar substitutes are gaining more and more relevance due to the health problems associated with the consumption of high amounts of sugar...I thought it would be interesting to take a few of those substitutes and acquire their proton NMR spectrum in our benchtop NMR.

Electronegativity and Chemical Shift

Electronegativity is a concept that we have to study and understand early in our science or engineering degrees. In chemistry this concept stays with us and we commonly invoke it in order to explain multiple phenomena what we observe or study…and of course, NMR is not the exception!

Lead NMR Spectroscopy

For many years tetraethyl lead was used as the principal fuel additive to enhance the octane rating of gasoline. In the mid-1970s the use of this substance was reduced because of the environmental hazards of lead and because it poisons catalytic converters. Nowadays, the main application of lead metal and lead oxide is in lead-acid batteries. In this application the cathode of the cell consists of lead dioxide packed on a metal grid and the anode is composed of lead metal. The electrochemical reaction is shown in the following equation:
