QM: two protons of H2 molecule

  1. Oct 20, 2012 #1
    Hey, I cannot solve this problem. Please help me.

    In the H2 molecule, the Pauli exclusion principle demands that the wavefunction of two protons
    be antisymmetric under the interchange of the two proton coordiates. Based on this, explain the
    (a) In the spin-triplet states of two protons (“orthohydrogen”), the orbital angular momentum quantum number associated with the relative motion of two protons is restricted to odd-integer values
    only.
    (b) In the spin-singlet state of two protons (“parahydrogen”), the orbital angular momentum quantum number is restricted to even-integer values only.
