我们提出了几种新的方法，可以获得固体中自旋1/2和半整数四极核之间的二维HETCOR光谱。这些方法使用旋转共振概念，通过偶极相互作用而不是标量耦合到HMQC中产生异核相干，并重新聚焦自旋n/2 （n > 1）的INEPT实验。与基于交叉极化转移到四极核的方法相反，该方法具有很强的鲁棒性和易于建立。(c) 2007爱思唯尔公司版权所有。
We present several new methods that allow to obtain through-space 2D HETCOR spectra between spin-1/2 and half-integer quadrupolar nuclei in the solid state. These methods use the rotary-resonance concept to create hetero-nuclear coherences through the dipolar interaction instead of scalar coupling into the HMQC and refocused INEPT experiments for spin n/2 (n > 1). In opposite to those based on the cross-polarization transfer to quadrupolar nuclei, the methods are very robust and easy to set-up. (c) 2007 Elsevier Inc. All rights reserved.
