Some common household products contain many NMR active nuclides able to provide information on the identify the major components of the product.  Toothpaste is such an example.  It contains abrasives, surfactants, cleansers, fluoride, sweeteners,...
Presaturation is one of the most common methods of solvent suppression.  A long selective low power pulse is applied at the solvent frequency followed by a hard non-selective read pulse (or composite pulse).  Aside from a well-shimmed homogeneous...
With the recent re-emergence of low-field NMR spectrometers at proton frequencies of 40, 60, 80 and 100 MHz, many younger NMR users (who have grown up with high-field spectrometers) are encountering more and more second-order spectra. These spectra are observed...
