The interaction constants in 13C and 2H nuclear magnetic resonance relaxation studies

Abstract

2H and 13C nuclear magnetic resonance relaxation data are presented for specifically deuterated and protonated sodium hexanoate, respectively. Analysis of the data yields the ratio between the 13C dipolar and 2H quadrupolar coupling constants. This ratio differs significantly from the value obtained from commonly used values for the constants. The 13C coupling constant is then evaluated theoretically and consequently the 2H quadrupole constant is obtained as well. Finally, some 2H and C NMR relaxation data for a sodium octanoate/water system are analyzed using the “traditional” values of the coupling constants and the values presented in this work.
