Chapter 6, Problem 71AP

The MO of the ground state of a heteronuclear diatomicmoleculeAB is

${\psi }_{\text{mol}}=C_{\text{A}}{\phi }^{\text{A}}+C_{\text{B}}{\phi }^{\text{B}}$

If a bonding electron spends 90% of its time in an orbital ${\phi }^{\text{A}}$ on atom A and 10% of its time in ${\phi }^{\text{B}}$ on atom B, what are the values of $C_{\text{A}}$ and $C_{\text{B}}$ ? (Neglect the overlap of the two orbitals.)
