SPIN DECOUPLING EXPERIMENT
« on: December 08, 2009, 11:05:08 AM »
in general interaction with neighbouring nuclear dipoles only causes a splitting of the signal if the nuclei maintain their spin orientation in B0 for a time longer than τ0=1/J but in spin decoupling experiment we try to shortening this time by irradiating with a second frequency v2 .
here I have 1 question:
 how does this 2nd radiator shorten this time?

I'm not completely sure of the answer, but could the second frequency be promoting stimulated emission?
