The focus of the Emmy Noether junior research group lies on the determination of the 3D structure of organic compounds and biologically active species by NMR spectroscopy (in orienting media). Information on the solution conformation and relative configuration is usually obtained from the angular dependence of 3J couplings and the distance dependence of the NOE. During the last eight years an additional NMR parameter, the residual dipolar coupling (RDC), was introduced. There are, however, hitherto very few applications on conformationally flexible compounds and on the determination of the absolute configuration. These aspects as well as the necessary methodological developments (in terms of alignment media, treatment of flexibility and determination of absolute configuration) will be covered within this junior research group.

艾美诺伊特初级研究小组的重点是通过核磁共振波谱(在定向介质中)确定有机化合物和生物活性物种的3D结构。关于溶液构象和相对构型的信息通常是从3J耦合的角度关系和NOE的距离关系中获得的。在过去的八年中，引入了一个额外的核磁共振参数，即剩余偶极耦合(RDC)。然而，到目前为止，在构象柔性化合物和确定绝对构型方面的应用很少。这些方面以及必要的方法发展(在对齐媒介、灵活性的处理和绝对构型的确定方面)将由这个初级研究小组负责。
