New versions of the H2BC pulse sequence (Nyberg NT, Duus JØ, Sørensen OW. J. Am. Chem. Soc. 2005; 127: 6154) that edit into two subspectra according to the number of protons attached to 13C nuclei being odd or even are introduced. These sequences can be useful for resolving spectral overlap, which is demonstrated on the molecule prednisolone [(11 beta)-11,17,21-trihydroxypregna-1,4-diene-3,20-dione].
引入了H2BC脉冲序列的新版本（Nyberg NT，Duus JØ，Sørensen OW。《美国化学会志》2005年；127：6154），该序列根据连接到13C核上的质子数是奇数还是偶数将光谱编辑成两个子光谱。这些序列对于解决光谱重叠可能是有用的，这在泼尼松龙[（11β）-11,17,21-三羟基孕甾-1,4-二烯-3,20-二酮]分子上得到了证明。
