Abstract

The two‐frequency pulse response of a multilevel system in NQR is investigated. Additional spin echo signals are shown to appear. The application of the two‐frequency spin echo method to some of the crystals is demonstrated. The method is of great value for the investigation of local fields in crystals.

Frequency-modulated rf pulses based on a linear frequency sweep are studied experimentally in spin-echo and stimulated-echo sequences. It turns out that these FM pulses generate a quadratic phase perpendicular to the selected slice and that the quadratic phases of the FM pulses in a spin-echo or sti

A series of the d 6 iron(I1) complexes with bulky organic ligands (like [ Fe(bzpy),(NCS),]) can exist in two spin forms: in the low-spin ( S = 0) form at low temperature and in the high-spin ( S = 2) form at high temperature. In the crystal phase, the transition between these two forms may be either
