✦ Synopsis

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 significantly enhanced compared with the four-pulse 2D ESEEM method of HSfer, Grupp, Nebenfiihr and Mehring. A single crystal of KCI doped with Fe(CN)63-is used to demonstrate this new 2D ESEEM spectroscopy together with an effective phase cycling scheme.

A new one-dimensional mixing-frequency electron spin echo envelope modulation (1D MIF-ESEEM) spectroscopy has been developed. It is based on use of the ratio of the increments of two evolution periods as an experimentally meaningful parameter. By means of this method, the separations of peaks can be
