[Pw_forum] Mos2 spin orbital coupling

[pourya]

Dear all
Hi,
I calculate spin orbital coupling for Mos2 but I do not know why the 
band dispersion is completely similar to non spin orbital coupling bands 
structure.
I will deeply appreciate you to give me some points to understand where 
my misunderstanding is.

Thanks in advance,
