Hi, In version 2_7_6049, I could simulate the effects of SRSK on a spin-1/2 spectrum when the relaxation rate of the quadrupolar nucleus was rather slow. For example in the 1H - 11B case, if used inter.relaxation={'t1t2', 'SRSK'} I could set r1/r2 for the quadrupoar nucleus to be of the order of the...

Dear Ilya, Thanks for the clarification, I see your point about timescales. I guess (although I am as you can see not super clear on the theory) that the breakdown of the theory doesn't mean that the effect is not there; rather that we can't quantify or predict it. I tried the calculations with the ...

Hi folks, I have done this, in a way that works, but needs some topspin fiddling, for both 1D and for some 2D data. This is a long post but a large chunk is the functions themselves. Once you have created a suitable topspin dataset for a given case you can just copy it and you only need to modify pa...

Dear Spinach community, I have a molecule undergoing exchange in which I wonder if the effects of scalar relaxation of the first kind are visible in 2D NOESY. There is definitely exchange, and I see a strong cross peak with same sign as the diagonal between two spins which are coupled (meta protons ...
