I have a quick question regarding the simultaneous use of gStrain and gFrame . When we use gFrame to define the g-tensor orientation, does the gStrain follow along, or does it stay with the lab frame? I suppose it should, but I didn't want to make any assumptions. Thanks! Note: I suppose the same qu...

In a (probably) related issue, FitOpt.PrintLevel seems to have no effect on the output's verbosity when esfit is invoked without the fitting GUI. Even setting to 0 produces the full output.

I have tried capitalization permutations (printLevel, Printlevel, printlevel) without luck.

I believe that the utility of this would be to use saturation effects on the line shapes as a poor man's pulsed EPR spectrometer to extract T1. E.g. rapid passage effects could be simulated to yield information on T1, instead of just being a nuisance. That being said, I don't know the complications ...

Yes, that was the issue!

I believe a correction should be made at the esfit documentation page downloaded with the latest version.

Thanks Stefan.

In equivalent terms, the problem at hand is the labeling of the spin states. As far as I understand, there is no consistent way to describe those, which is why Easyspin numbers them by increasing energy at each magnetic field.

Size inputs must be integers.

The error comes from inclusion of Sys.n.
First: This is for garlic.
Second: It must be an integer.

So, I played around and managed to find a partial solution based on the type and tag attributes of the lines and texts. For anyone with the same issue, the following hack works ex post for two orientations (a more generic version would be needed for an arbitrary number of orientations but I scratche...

In a system with C, H and N nuclei, the following had worked for me: Sys.Nucs = 'N,H,C'; Sys.n = [1,12,4]; Sys.A = [40.95 0.695 17.85] Sys.lwpp = [0.0136 0.0203] From a rapid glance, it seems you are on the right track. If I had to guess, I would say that your line widths are too large with respect ...

I am resurrecting this thread as I am trying to make a Zeeman plot with custom colors. While I had managed to make things work with the previous approach, that was a rather special case involving relatively few levels and not many level crossings. I am now dealing with a system with significantly mo...

Try changing the order of the arguments:

Code: Select all

esfit(spc,@pepper,{Sys0,Exp},{SysVary});
