I used VMI for the photodissociation of O2 and I wonder how I can correlate the radius with the actual velocity of the fragments. Thanks a lot!

  • $\begingroup$ Thanks Kyle Kanos, you are right! @mmesser314, I cannot figure how, for example in the second link, the pixel radius is correlated to TKER, is there some universal conversion factor? $\endgroup$ – Chris Dec 7 '19 at 14:24
