NMR spectroscopy is a physicochemical analysis technique that is based on the interaction of an externally applied radiofrequency radiation with atomic nuclei. During this interaction there is a net ...

Investigation of mass-limited samples can also benefit from the reduction of the sample volume in miniaturized coils, since the amplitude of the NMR signal is optimal when the sizes of the coil and ...

NMR spectroscopy is a powerful technique that is ideally suited to the characterization and analysis of a diverse array of chemical compounds. Unlike many other analytical techniques, NMR spectroscopy ...

Artemisinin is a drug commonly used to treat malaria. The drug can be produced in a semi-synthetic manner, or it can be extracted from the plant Artemisia annua (sweet wormwood). Figure 1 displays the ...

Please prepare your samples in the designated area or under a hood, and not on top of the magnet. The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the ...

The content of hydrogen in a sample is determined by measuring its hydrogen content by weight. Be it before or after refining, the determination of this parameter is crucial in various oils because it ...

This case study demonstrates how advanced NMR spectroscopy enables high-resolution structural characterization of exenatide.

Anasazi Instruments offer the sturdy, high quality and convenient 60 MHz and 90 MHz NMR spectrometers, in addition to upgrades to industrial and educational markets. These instruments are being ...

qNMR Using PULCON Use this document to perform quantitative NMR (qNMR) experiments using the PULCON methodology. This technique allows you to obtain concentration information about your NMR sample ...

Unfortunately, many 1H-NMR spectra are severely overlapped due to the multiplet structure caused by homo-nuclear scalar couplings. "Pure shift" NMR spectra, also known as broadband homonuclear ...
