You system has two spin entities, a s=2 and an s=1/2, but Sys.nucs and Sys.A has three entries. That does not match - only one nucleus can be associated with each spin centre.

Optimising simulations to match data from non-standard setups
Dear Easyspin Community I have, with limited success, been trying to optimise the match between simulations and data measured on a home-built HF EPR setup. My data is measured with frequencies between 128 and 660 GHz. My collaborators told me that the the instrument was setup in a "double-pass&...

Re: Assistance Required in Defining Spin for a Metal Radical System in Easyspin
If each ligand has one electron delocalised across its pi system, you simply model by a single s=1/2. So one s = 3/2 and three s=1/2 in total.

Spatial dependence of dipolar interaction?
Dear Easyspin community I wonder, how is the spatial dependence of the dipolar interaction implemented in Easyspin? Usually, the dipolar energy between two magnetic moments is defined by their dot product as well as their projections along the vector that separates them. For example, consider four s...

User-defined Hamiltonian algorithm for "curry"
Dear Easyspin community Is there any way to use a user-defined Hamiltonian to compute magnetic data of a spin system using "curry"? I have written an algorithm to add another interaction to the matrix generated by "ham" and I would like to compute the magnetism of the resulting s...

Re: Seeking suggestions to fit EPR spectrum of a Fe(III) complex having both high-spin and low-spin components
What I mean is that Easyspin clearly adds a significant baseline correction to the fitted spectrum. The curvature of the green line at the largest B-fields is from the baseline, not from the spectrum. I think the baseline added to the calculated spectrum may distort the relative intensities of the c...

Re: Seeking suggestions to fit EPR spectrum of a Fe(III) complex having both high-spin and low-spin components
It looks like your fit has at a quite hefty baseline correction. Does the problem persist without baseline, or if the baseline is restricted to a constant?

Re: Different Line Width for Different Transitions?
Thank you once again! I was not aware these features were built into Easyspin. I even found 'convspec' which produces the line shape and does the convolution all in one line.

Re: Different Line Width for Different Transitions?
Follow-up question: I use Matlab's "normpdf" to generate a gaussian array for the convolution and "conv" with the kwarg "same" to perform the convolution. However, I find that the resulting spectra depend on my x-array spacing in the pdf array. Am I doing something wron...
