Nuclear magnetic resonance is an analytical way of carrying out a particular task, especially the execution or performance of an artistic work or a scientific procedure of chemistry that is used in determining the content and purity of a sample as well as its molecular structure and in quality control and research. This is a test that can detect the structure of a product at the molecular level. Under Indian law, NMR testing is not necessary for honey that is marketed locally, but this test is necessary in the case of exports.
