Gas‐phase NMR studies of chemical equilibria: 1—Methodology
作者： Robin K. Harris , Renée C. Rao
关键词:
摘要: Methods for obtaining 1H NMR spectra of gases are discussed. Particular attention is paid to the nature tube and use ‘second sample’ field/frequency locking. The question chemical shift reference examined, some results tetramethylsilane gas presented. Representative shown three types organic equilibria in phase: keto-enol tautomerism, addition methanol acetaldehyde Z-E isomerism acetaldoxime.
