Re: Chemical exchange- how to?

I have made some minor changes in the code. Now general methods (1 and 2) seems to be working with separate lw for each site and arbitrary population. May I publish the code for testing in the corresponding topic?

Re: Chemical exchange- how to?

Thanks a lot for amazing program. I have some questions about it. 1. Sys.xc parameter is not described enough. I propose that it defines the order of the nuclei in the second and futher sites. Is it right? 2. It is not completely clear how to define exchange rate contants. For example, for two-site ...

Chemical exchange- how to?

It seems that EasySpin can simulate cw spectra with chemical exchange broadening (J. Phys. Chem. A, 2013, 117 (7), pp 1439–1448 DOI: 10.1021/jp3104358). Unfortunately, there are no any documentation about this feature. Is it possible to provide some examples for this topic?

Re: Vanadium 51 Trouble: PLEASE HELP!!

Try this script:

Sys.S = 1/2;
Sys.g = [1.9875 1.9835 1.9510];
Sys.lwpp = .5;
Sys.Nucs = '51V';
Sys.A = [175 180 505];
Exp.Harmonic = 1
Exp.mwFreg = 9.78;
Exp.Range = [260 440];
Exp.nPoints = 2048;
pepper(Sys,Exp);

Re: How does FitOpt.Plot option works?

I think, it should be better to keep such feature for clarity.

Re: Dimensions of return values from eprload and esfit

Thanks. I used reshape function to override this inconvenience.

How does FitOpt.Plot option works?

I try to run esfit function with FitOpt.Plot=1 in this manner:
....
FitOpt.Plot=1;
[bestfit,bestspc] = esfit('garlic',y,Sys,Vary,Exp,[],FitOpt);
....

But there are no graphics appear. What I'm doing wrong?

Dimensions of return values from eprload and esfit

The function eprload returns x and y values in different dimensions. The x values return as <1 x nPoints double> whereas y ones return as <nPoints x 1 double>. Moreover, esfit returns y values as <1 x nPoints double>, it makes certain inconvenience.
