摘要: TOCSY可提供自旋网络中全部质子的接力信息,是RELAY的新发展,它特别适用于具有若干独立自旋系统的大分子.
本文在同核和异核相关实验中均用MLEV-17序列进行全面相关,并对两种多肽进行了分析.

关键词: TOCSY, RELAY, 多肽, 分析

Abstract: TOCSY which provides relay informatoins overall protons in spin coupling network is a new development of RELAY. It is especially suitable for large molecules which have several independent spin systems.
In this paper, MLEV-17 sequence has been used for TOCSY both in homo-and heteronuciear coherence experiments and two polypeptides have been analysed.

Key words: TOCSY, RELAY, Polypeptide, Analysis
