Re: Rotview negative angles

I would say that +/- 360 degrees would come in handy. Certainly, that would cover each rotation dimension twice over, but sometimes fits of frames end up at negative rotations and it would be nice to be able to visualize them manually.

Re: How to include J/ee between two systems

While I understand this aspect of Easyspin, the question is interesting in cases of two weakly coupled (e.g. dipole-dipole) systems of widely differing intrinsic relaxation properties. E.g. two systems with very different spin-lattice relaxations, or very different linewidths. I am not sure there is...

Rotview negative angles

A very minor bug for rotview: the graphical output of does not accept negative rotations, although the command line invocation can accept, calculate and plot them just fine.
It is the sliders in the plotted figure that cannot handle negative values.

That's all!

Matrix block diagonalization

Hello,

I would like to do a curry calculation of a very large system (five Gd(III) ions). Fortunately, the system is isotropic, so block diagonalization of the Hamiltonian is a valid approach.

Does ES do this, either automatically, or through an option?

Thanks!

Re: Cu and 51V simulation attempts

Seems like fluid solution spectra?

The first is simulated with pepper (which is for powders and frozen solutions) and the latter with garlic, but without defining a tcorr.

Maybe try out garlic with tcorr?

Re: Orientation/field-dependent line widths

You may see that the flat parts of the simulations do not follow the parts where Tm has drop-offs.

Re: Orientation/field-dependent line widths

Here are the spectra files and a fitting script.

Orientation/field-dependent line widths

I am trying to simulate spectra such as reported by Eaton & Eaton here . The main idea is that Tm times are orientation-dependent, hence in frozen-solution spectra they are effectively field-dependent. To the extent that line widths are Tm-determined, the net effect is that they will be differen...

Rescale function error

I am running a fit using a custom function. Naturally, after the pepper invocation in the custom function I use a rescale command to rescale the calculated with the experimental y-values. [x,y] = pepper(fullSys,Exp,Opt); y_ref = Sys.spc; y_rescale = rescale(y(:), y_ref(:), 'lsq0'); On a Linux machin...
