SUMMARY

The discussion focuses on the verification of eigen solutions for the H2 molecule, specifically addressing the equations governing the wavefunctions of two hydrogen atoms. The equations presented are derived from quantum mechanics, utilizing the Hamiltonian operator for each atom: (\frac{p^2_1}{2m}-\frac{e^2}{2\pi\epsilon_0r_{1a}})|\varphi_a^{(1)} \rangle=E_a|\varphi_a^{(1)}\rangle and (\frac{p^2_2}{2m}-\frac{e^2}{2\pi\epsilon_0r_{2b}})|\varphi_b^{(2)} \rangle=E_b|\varphi_b^{(2)}\rangle. The resulting combined wavefunction |q \rangle^{(\pm)} is identified as a crude approximation of the true wavefunction, specifically the Valence-Bond or Heitler-London wavefunction, rather than the exact spatial part of the H2 molecule's wavefunction.

Eigen - problem for atom ##1##
[tex](\frac{p^2_1}{2m}-\frac{e^2}{2\pi\epsilon_0r_{1a}})|\varphi_a^{(1)} \rangle=E_a|\varphi_a^{(1)}\rangle[/tex]
for atom ##2##
[tex](\frac{p^2_2}{2m}-\frac{e^2}{2\pi\epsilon_0r_{2b}})|\varphi_b^{(2)} \rangle=E_b|\varphi_b^{(2)}\rangle[/tex]
When I write
[tex]|q \rangle^{(\pm)}=\frac{1}{\sqrt{2}}(|\varphi_a^{(1)} \rangle|\varphi_b^{(2)}\rangle \pm |\varphi_a^{(2)} \rangle|\varphi_b^{(1)}\rangle)[/tex]
did I get the space part wavefunction of hydrogen molecule ##H_2##?

No, what you get is a crude approximation (the Valence-Bond or Heitler-London wavefunction) for the spatial part of the true wavefunction.
