The stability of the magnetic field is an important factor in NMR spectroscopy. Field drifts over the course of a long experiment lead to artifacts in the data. These can manifest themselves as additional line broadening in 1D spectra, as well as vertical stripes (the so-called T1 noise) in a 2D spectrum. High frequency stability …
There is an interesting effect when you try to measure 13C spectra of fluorinated hydrocarbons. Take for example 1,4-difluorobenzene. This is a benzene molecule where two opposite protons have been replaced by fluorine atoms, as shown by this structure:
As costs for energy and raw materials continue to rise, it becomes more critical for chemists to be able to mimic a reaction or to quantify the parameters required to produce a final product without the difficulty and expense of using production facilities. To be able to recreate a production process on a lab bench …
