Error from Using easfit with Multicomponent

I've an error when I constructed 2 systems in easyspin-5.2.25 that affacted by few protons. Here is my code clear all clc; [numbers,strings] = xlsread('RAWDATA','RAWDATA'); XDATA = numbers(:,1); YDATA = datasmooth(numbers(:,3),40,'binom'); FitOpt.Method = 'simplex'; FitOpt.Scaling = 'maxabs'; AmT2MH...

Re: Difference of Landé g-values at different radical posit

I changed manually in quantum chemistry program. It reported g tensor different when I change position of C-atom on glucose ring. What is the reason of position dependence for g tensor? For hyperfine tensor,is it relate to C-atom position or surrounding protons or O-atom in the molecule?

Difference of Landé g-values at different radical position

Dear all members, I have a question about Landé g-value in hyperfine interaction. When I fixed a single molecule, such as, glucose and I changed radical position from C(1) to another, g-values are different. Are there effects of magnetic filed interaction between surrounding protons (since O-16 and ...

I have a problem for many systems that containing "A" values

I have found that the code was error after I write a code for 6 systems by using pepper function. In each system contains hyperfine coupling constant tensor by dependence to nucleus of hydrogen. Then I run the code, there is error code that I gave " Error using pepper The system contains A and/...

What should I simulate the ESR spectrum of rice

I'm going to simulate the ESR spectrum of rice as a solid sample by using the modified code from somewhere in this forum. My code is shown as clear all [B,spc]=eprload('LMU_9JUNE2017.DTA'); % isotropy g_G1xy = 2.005018556; g_G1z = g_G1xy; g_G2xy = 2.003566917; g_G2z = g_G2xy; %% line width lwGL1 = 1...

How can I show the exact EPR spectrum in fitting panel

Hi! everyone. I'm trying to fit my experimental result from EPR spectrometer by EasySpin on MatLab. My spectra file were saved in form .DTA and .DSC. So, I wrote MaTLab for analysis this following by the code clear [spc,Params,B] = eprload('1KGY1OCT2016.DSC'); spc = addnoise(spc,0.000000000000000000...
