Improvements to selective refocusing phased (SERFph) experiments
چکیده انگلیسی
Selective refocusing experiments are very powerful for extracting proton-proton couplings one by one. However we demonstrate in the present work that various spectral artefacts are produced by the initial sequence and we show that the combined addition of a refocusing π pulse and a zero-quantum filter greatly improves the experimental sensitivity, and moreover leads to observation of pure absorption lineshapes in the resulting phased 2D spectrum. These developments are applied to the differentiation of enantiomers dissolved in a chiral liquid crystal.
