51V EPR simulation

Post by Chanchal »

Hello all,
I recently started using Easy spin by following the steps mentioned in the Prof. Stefan Stoll video lectures.
I need to simulate the following EPR spectra of a vanadium complex
A starting code for the spectra will be appreciated.
Thank you for the help

In the particular spectrum you posted, it looks like you might have some baseline issues (left baseline and right baseline are not zero). That will make it difficult to fit the spectrum with EasySpin.

I am also facing the same baseline issues (left baseline and right baseline are not zero). It will be helpful if someone can help me regarding this type of baseline correction.

In my opinion, If it considered that there is linear decrease on the above EPR spectra, one can use "originlab" software with subtract line option (Analysis:Data Manipulation:Subtract Straight Line).

Thanks Seradir,
I have solved the problem in my case. Actually the background is coming from my substrate on top of which I have deposited my sample. So in that case I have substracted the substrate from my actual sample data like below:

%Imports Data, then the background and subtracts out the background
[B1, spc1, Params1] = eprload('Sample.DTA');
spc2 = spc1;
Params = Params1;
[B3, spc3, Params3] = eprload('Substrate.DTA');
spc = spc2 - spc3;

Hope, I am correct and this will help someone.

Thanks,
Sangita
