Abstract

Isotropic mixing sequences are one of the key methods to achieve efficient coherence transfer. Among them, the MOCCA-XY16, which keeps the magnetization longitudinal for a significant amount of time, is characterised by favourable relaxation properties. We show here that its adapted version is particularly suited for carbonyl-carbonyl correlations in (13)C direct detection NMR experiments.

摘要

各向同性混合序列是实现高效相干转移的关键方法之一。其中，MOCCA-XY16能使磁化强度在相当长的时间内保持纵向，具有良好的弛豫特性。我们在此表明，其改进版本特别适用于（13）C直接检测核磁共振实验中的羰基-羰基相关性。
