Switching of the partially negative line effect of orthohydrogen via solvent types and their binary mixtures

Tomasz Ratajczyk – @TRatajczykonX

Under specific conditions, orthohydrogen generated from parahydrogen can appear to have a partially negative 1H-NMR line (PNL). We present that in some solvents, PNL appears with a positive-negative pattern, while in others, PNL has a negative-positive pattern. The modulation of PNL in a mixture of various solvents will be discussed.
