EasySpin forum

Hello,

I want to calculate the energy spectrum in zero applied field. I know about "levels" function, but it allows only to calculate the energy levels evolution in an applied field. Is it there anyway how can I do it in absence of any field? In other words I just want EasySpin to give me the eigenvalues of my Hamiltonian.

Many thanks in advance!

gives you the eigenvalues of the Hamiltonian of the system Sys in zero field.

Thanks a lot! It worked.
