Hello
We conducted an experiment recently for our physics lab to determine the relaxation times for a solution of Fe3+ and Mn2+ ions we then had to compare the ratios of T1/T2 for the two solutions and we found that for Fe3+ ions the ratio came to ~1 and for Mn2+ ions it came to 4 (i.e >1)
My question is why is there a difference in the ratios? It seems that it is all dependent on T2 (relaxation time eliminating field inhomogeneity). I've been hearing things about scalar coupling but I don't understand that idea fully. :-/
