EasySpin forum

Thanks a lot for your work on this.

I assume the reference point is always the isotope with the greater natural abundance? Then, as you have shown, it scales with nuclear g value.

Hello,
For CW simulation, if I don't state the isotope and give one hyperfine value how does Easyspin assign the hyperfine values? For example, if I write Cu and give it a value of 150 MHz. What hypefine values will Easyspin assign to 63Cu and 65Cu?

Thank you and best wishes,

James
