51V multiple oxidation states function Chili

[yananwang1991]

Dear All,

I just have a quick question, for EPR spectra of vanadium oxide compounds, if I measure the spectra in solution phase under Room temperature,
The function I need for fitting is Chili right?

Thank you.

That depends on the rotational correlation time (Sys.tcorr), i.e. how fast the molecule is tumbling, which in turn depends on how large it is and how viscous the solution is, and on the temperature.

For rapidly tumbling molecules, you can use garlic, otherwise use chili. garlic treats the special case of fast rotational motion and is computationally faster than chili. chili has the reference method and works for both fast and slower rotational motions.
