Diatomic energy Transfer

Nuklear99

I think I have a somewhat simple question but I can't seem to find the answer online.. I know that the internal energy of diatomic molecules is presumed to be equally shared in the rotational and translational degrees of freedom.. My question is this...

Do Diatomic gas molecules convert some translational velocity into angular velocity & vice versa? I'm guessing that individual molecules have varying rotating and linear speeds. So I'm wondering if my assumption is correct that one molecule's linear velocity can change the angular velocity of another; possibly it increases it's own angular velocity in the process??? I don't know..

Any clarification here would be much appreciated, Thank You..
