If the 180 degree pulse gives a clear null then I suspect that you have little if any radiation damping. The decrease in intensity for the longer pulses may be due to B1 inhomogeneity in the coil of your probe.

I have a question about evaluating radiation damping from a nutation curve. With heavy radiation damping, the effect on the nutation curve is very obvious, but can you evaluate the degree of radiation damping by observing any deviation from sinosoidal behavior? I have a nutation curve whose 180 is clear, but the intensities of the higher degree peaks is quite a bit less.<br /><br />Thanks,<br />JoeAnonymousnoreply@blogger.com
