EasySpin forum

Hi all,
I would like to ask about the Wigner-Eckart theorem. Are Wigner-Eckart theorem and Reduced Matrix Elements included in the calculations? I am interested in 4fⁿ, and 5fⁿ ions ( lanthanides and actinides). Wigner-Eckart theorem and Reduced Matrix Elements are very important.
Best wishes for creators of EasySpin and forum participants.

Hello! Can you clarify which type of operators you would like to include? EasySpin provides matrix elements for many angular-momentum operators through the function sop - have a look.
