A new six-pulse two-dimensional electron spin echo envelope modulation (2D ESEEM) method is introduced. It is based on augmenting the five-pulse sequence proposed by Gemperle, Schweiger and Ernst with an additional rr pulse. It is shown that the intensity ratio of cross peaks to diagonal peaks is si
## Abstract The application of a Hahn spin–echo extended X–^1^H shift‐correlated (X = ^13^C, ^29^Si, ^119^Sn, ^207^Pb) two‐dimensional NMR technique to carbon–, silicon–, tin– and lead–nitrogen compounds is described. This allows complete suppression of the central line (representing the isotopomer
