Examples of 'chemical shifts' in a sentence
Meaning of "chemical shifts"
Chemical shifts are used in the field of nuclear magnetic resonance (NMR) spectroscopy to describe the position of a signal in the spectrum. It is a measure of the difference in frequency between the resonance of a particular nucleus and a reference standard. Chemical shifts are influenced by the local electronic environment of the nucleus and can provide valuable information about the structure and environment of molecules
