Hello, I’m having trouble simulating this azurite spectrum.
I need the peaks on the left side to merge and form a broad band, but when I increase the Line Width, the lower peak on the right loses resolution, and instead of forming two small distinct peaks, they merge into one.
How could I create a broad band on the left while keeping the resolution on the right?
Below is the script I'm using:
% Import data
[B,spc] = textread('AzuriteFile.txt','%f %f');
% [B,spc] = textread('file name.txt','%f %f');
plot(B,spc);
% Simulation parameters
Exp.mwFreq = 9.5; % Microwave frequency (GHz)
Exp.Range = [min(B) max(B)]; % Magnetic field range (mT)
Exp.nPoints = numel(B); % Number of points in the spectrum
% Experimental parameters
Sys0.Nucs = 'Cu'; % Paramagnetic nucleus
Sys0.n = 1; % Number of nuclei
Sys0.g = [2.32 2.09 2.085]; % g-tensor values gz, gy, gx
Sys0.A = [510 20 15]; % Hyperfine coupling A (MHz)
Sys0.lwpp = 3.0; % Line width (MHz)
% EPR spectrum simulation
Vary.g = [0.05 0.05 0.05];
Vary.A = [0.1 0.1 0.1];
Vary.lwpp = 0.01;
esfit(spc,@pepper,{Sys0,Exp},{Vary});
