✦ Synopsis
Spin-7/2 central line intensities are calculated for any ratio of the quadmpolar coupling constant to the radiofrequency field for both one-pulse and two-pulse Hahn-echo experiments and tested by 59Co NMR on the model compounds, Na,[Co(NO,),] and trans-[Co(en),(N0,)2]N03.
The Hah -h n ec o se q uence is then used to obtain the quadrupole coupling constant and asymmetry parameter on a powder sample of Co,(CO),,. This technique is found to be particularly useful when the NMR spectrum is broad and featureless. 0 1997 Elsevier Science B.V.
