Abstract
A method is developed for measuring the content of hydrogen (2Н) and oxygen (17O) isotopes in liquid media based on quantitative nuclear magnetic resonance. It has been established that the shifting europium trifluoromethanesulfonate (III) reagent is the most appropriate chemical compound for a reference sample to study the isotopic composition of aqueous solutions. A dependence of the paramagnetic chemical shift of 2Н and 17O nuclei on the concentration of Eu3+ ions in a solution is studied.
