We report NMR relaxation time measurements of the 14N quadrupole coupling parameter χN of isocyanomethane as a function of temperature in the solution-state mixture of 6.4 mol % H3CN ≡ C, 33.5 mol% d6-ethylene glycol, and 60.1 mol % d6-ethanol. We obtain values for the molecular correlation times using the T2/T1 method, which is a function only of the spectral density functions. The results demonstrate a significant, and approximately quadratic, temperature dependence of χN, which shows a minimum value of about 55 kHz at 222 K; the largest value measured was 125 kHz at 161 K. The results are compared with, and discussed within the context of, more traditional methods. The value of χN for neat isocyanomethane in the solid phase was measured to be 26.3 kHz. © 1995 American Institute of Physics.
