摘要:
Abstract1H n.m.r. is used to show that α‐mercaptoacetone is formed as a mixture of monomer and a dimer. No evidence is found to support the previously claimed isolation of two dimeric species. The dimer dissociates to the monomer on standing as a solution in chloroform, but the monomer is dimerized by grinding. 1‐Mercapto‐3‐phenylpropan‐2‐one behav

摘要:
AbstractSelective pulsed excitation was used in a technique to suppress the resonance due to a per‐12C‐isotopomer so as to overcome dynamic range problems when observing ‘13C satellite’ lines. The technique was used to obtain nuclear spin parameters from the13C satellites in31P resonance for the racemic isomer ofP,P′‐dimethyl‐P,P′‐diphenyldiphosphine disulph
