WebNMR Spec Question - Lower Integration Value Than Reference. After generating an NMR of myristic acid from the saponification of trimyristin I get an integration value for the tall peak (at roughly 1.3ppm, protons B-K) of 10.5, but the reference value for this peak should be 20 because there are 20 such protons in the myristic acid.

As of 2006, the most precise measurement of R had been obtained by measuring the speed of sound ca(P, T) in argon at the temperature T of the triple point of water at different pressures P, and extrapolating to the zero-pressure limit ca(0, T). The value of R is then obtained from the relation where: • γ0 is the heat capacity ratio (5/3 for monatomic gases such as argon);
