Re: Effect of J and eeD on the powder spectrum with S=1/2

Oops I have Sys3 as being axial, here is the rhombic equivalent Sys.S=[1/2 1/2]; Sys.g=[2.05,2.1,2.2;2.05,2.1,2.2]; Sys.lw=1; Sys.J=0; Sys1.S=[1/2 1/2]; Sys1.g=[2.05,2.1,2.2;2.05,2.1,2.2]; Sys1.lw=1; Sys1.J=10; Exp.mwFreq=9.79; Exp.CenterSweep=[350, 100]; Sys2.S=[1/2 1/2]; Sys2.g=[2.05,2.1,2.2;2.05,...

Re: Effect of J and eeD on the powder spectrum with S=1/2

Hey Dr. Stoll! My name is Jeff Monroe I work at Clark University for Dr. Mark Turnbull and I am very grateful that you've replied to my post. I love EasySpin, it's so cool thank you! I'm relatively new to EPR, EasySpin and coding so if I've made unforgivable mistakes I apologize in advance. Our grou...

Effect of J and eeD on the powder spectrum with S=1/2

Hello All! I'm working on simulating powder spectra of low dimensional copper(II) lattices and I have a couple general questions I'm hoping you can answer. The general code scheme I've been using is very simple with some number of S=1/2 ions with axial or rhombic gs thus: Sys.S=[1/2 1/2 1/2....] I h...

Re: Line broadening from J(ee,dvec,etc.)

Joscha, Thank you for your quick reply. I'm sorry for the lack of details, I'm kind of new to this. 1.) I have tried with both one and two spins, however I have set their g values equal to eachother because as far as I know they should be identical. Also, I'm simulating powder spectra with rhombic g...

Line broadening from J(ee,dvec,etc.)

Please Help! I'm trying to simulate some weakly interacting Cu2+ cw-EPR spectra using pepper, but it doesn't seem like J or ee changes the lineshape/width at all, yet as far as I know it should. What am I doing wrong? using something like this Sys.g=[2.19,2.1,2.04] Sys.J=100 (then varied) or with ee...
