Dear Easyspin comminity I have recently started working with actinide ions, and have therefore started building Hamiltonians directly from the L and S quantum numbers. In this case, the crystal field (CF), in the form of Steven's operators, act on L rather than S . Thus, Easyspin now parametrises th...

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.

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&...

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.

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...

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...

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...

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?

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.
