Coherence-transfer table: A convenient method for deriving coherence-transfer pathways of an NMR pulse sequence. I. Coherence-transfer table in I-x, I-y, and I-z system

A method for deriving coherence-transfer pathways of a nuclear magnetic res onance (NMR) pulse sequence in a table format, called a coherence-transfer table, has been developed. This method provides a convenient and easy-to-un derstand means to describe coherence transfers. In a coherence-transfer tab le, coherence at any time point, all the coherence-transfer pathways, and t heir NMR signals can be easily found. The coherence-transfer table method h elps in understanding the effects of phase cycling. It is very useful in an alyzing various multidimensional NMR pulse sequences. (C) 1999 John Wiley & Sons, Inc.
