Abstract

A pulse sequence DEPTQ yielding the signals and multiplicity information for all carbon types including the signals of quaternary carbons and encompassing all the known advantages of the basic DEPT experiment is proposed. Its behavior has been studied theoretically and experimentally and has been compared critically with alternative methods dedicated for the same purpose. Its marked insensitivity to experimental parameters and its potential for complete and efficient spectral editing makes DEPTQ the ideal experimental platform for a semi- or fully automated analysis of 1D 13C spectra.

摘要

提出了一种脉冲序列DEPTQ,它能产生所有碳类型的信号和多重性信息,包括季碳信号,并涵盖了基本DEPT实验的所有已知优点。已从理论和实验上研究了其性能,并与用于相同目的的其他方法进行了严格比较。DEPTQ对实验参数明显不敏感,且具有完整高效的光谱编辑潜力,使其成为一维¹³C光谱半自动或全自动分析的理想实验平台。
