Recently I asked this question and given the number of upvotes and comments I think that there are quite some people interested. However, it seems from the comments and the lack of answers that the question might have a more chemical answer.
Would it be ok to cross-post it on chemistry.SE and report the answers (if any) on physics.SE as well? Or should I perhaps flag for migration?
The reason I am wondering about cross-posting is that, given the interest on physics.SE, it seems a bit illogical to migrate the questions, because the users at physics.SE can nog longer find the answer.
