Double Quantum NMR in Solids

概要

論文の詳細を見る
In this paper double quantum NMR of deuterium in solids is described. By Fourier transformation of the time evolution, detected by a suitable train of pulses, a high resolution spectrum devoid of quadrupole splittings and broadning is obtained. The experiment is performed to a single crystal of oxalic acid dihydrate enriched to〜10% in deuterium and the chemical shift anisotropy of the carboxyl deuteron is estimated to be Δ^σ=32±3 ppm.
