提出了一种脉冲序列DEPTQ，它产生了包括季碳信号在内的所有碳类型的信号和多重数信息，并包含了基本DIFT实验的所有已知优点。它的行为经过了理论和实验的研究，并与专门用于相同目的的替代方法进行了严格的比较，其对实验参数的显著不敏感性以及完全和有效的光谱编辑的潜力使DEPTQ成为半自动或全自动分析一维C-13谱的理想实验平台。(C)1998年学术出版社。
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 DEFT 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 C-13 spectra.
