In the average case one can simply dissolve an analyte in an appropriate deuterated solvent and acquire a simple 1D spectrum to obtain all the required structural information. However, sometimes doing so may not provide you with all of the information you need!

NMR spectroscopy is by far the most useful characterization technique in organic chemistry, especially if you have to elucidate the structure or configuration of your products. Arguably, 2D experiments such as COSY, HSQC, and HMBC have simplified this task tremendously. In this post I wanted to highlight the COSY of α-humulene. Read more.

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).

What is process analytical technology (PAT) and why is it so important?PAT is an extremely powerful and useful tool for analyzing, optimizing and controlling chemical processes. Chemical, food and pharmaceutical industries could especially benefit from this technique. In earlier days, chemical processes were primarily monitored by physical techniques, such as temperature, pH, pressure etc..

Last month (which you can see here), we learned about how an acidic proton behaves in a 1H NMR experiment, particularly when it’s surrounded by D2O. For example, when an H+ leaves CH3COOH to join an accommodating D2O molecule, the resulting acetate (H3CCOO–) segment is reasonably comfortable bearing that negative charge. This phenomenon is the reason the solution is “acidic” in the first place. But why is acetate so capable of dealing with this negative electronic charge?

Distortionless Enhancement by Polarization Transfer (DEPT) is a double resonance pulse program that transfers polarization from an excited nucleus to another – most commonly 1H → 13C. This results in a sensitivity enhancement relative to the standard decoupled 1D carbon spectra (13C), which benefits only from the small Nuclear Overhauser Effect (NOE) enhancements.

2,4-pentanedione (aka acetylacetone, acetylacetonato or acacH) is not only a ubiquitous ligand (AND ligand precursor!) for beautifully coloured organometallic complexes[1-3].. Read more.

In November 2014 Nanalysis was pleased to announce the expansion of their product line with the NMReady-60PRO.  With this we also extended our experiment library for the NMReady-60e

Sustainability has become a main focus of innovation.  Topics of green chemistry, and renewable feedstocks, are paramount in society today.  Biodiesel is one such example!  Read more.

Learning about the parameters that are vital for obtaining good spectra – a concept that I had learned about in a theoretical sense, but as a synthetic chemist rarely thought about when collecting routine data.
