An Investigation of the Structure of Acetic Acid and the Mixture Acetic Acid/CCI4 by the Nuclear Magnetic Relaxation Method

Abstract

AbstractIntermolecular proton magnetic relaxation rates of the methyl and hydroxyl group of acetic acid involving the magnetic interaction among the various groups are reported. The data are given as a function of the mole fraction in the mixture acetic acid/CCI4. From these experimental results model atomic pair distribution functions and model molecular pair distribution functions are derived. It is shown that in the pure acid OH and CH3 never approach closely towards one another. At mole fractions x2 ≤ 0.3 the classical dimer can be observed which, however, appears in a more or less folded form.
