Examples of 'chemical shift' in a sentence
Meaning of "chemical shift"
chemical shift - In chemistry, this term refers to the change in the resonance frequency of atoms in a molecule due to their electronic environment. It is commonly used in nuclear magnetic resonance (NMR) spectroscopy to identify and analyze chemical compounds
