Do two hydrogens with same spin make H_2 ?

  1. Nov 29, 2011 #1
    As I know from the laws of chemistry,to form H_2 the H atoms must have opposite spin.
    What if they have the same spin?
    I mean, can an H atom rotate to swap his spin (i'm not expert of the dynamics of spin), or there is no way to couple them?
    In the case I have a gas of H with all of them polarized in the same direction is the formation of H_2 possible?

    What spin are you talking about? Electron spin?
