Abstract
We analyse the effect of the average dipolar field on an NMR J-doublet . This effect is twofold: an overall shift of the spectrum and a cross -precession between its components, which results in different intensi ties for these components, whose ratio depends on the pulse angle. Exp eriments on di-isopropyl ether at 500 MHz confirm these predictions. I n a thin elongated sample, a maximum intensity ratio of 1.09 is observ ed.
