In general, if the first RF-pulse has flip angle α1 and the second has flip angle α2, the maximum signal intensity of the Hahn echo will be smaller than the conventional (90°-180°) echo by a factor of (sin α1)•(sin² α2/2).The...

Hahn‐T2We studied the time course of changes in the Hahn spin-echo decay (Hahn-T2) in lungs of spontaneously breathing living rats at 1 hour, 3 hours, and 7 days following oleic acid injection. Motion artifacts were minimized by using the motion-insensitive interleaved rapid line scan (ILS...

Hahn-echo extended (HEED) pulse sequences in one- and two-dimensional experiments were successfully applied to phosphorus–nitrogen compounds with two PN bonds {2-chloro-1,3-dimethyl-1,3,2-diazaphospholidine (1), 2-tert-butyl-1,3-dimethyl-1,3,2-dizaphospholidine (2), bis(diethylamino)...
