Imagine a small electron-sensitive probe of volume 1.00 pm3 inserted into an H+2 molecule-ion in its ground state. Calculate the probability that it will register the presence of an electron at the following positions:

(a) At nucleus A,

(b) At nucleus B,

(c) half-way between A and B, (c) at a point 20 pm along the bond from A and 10 pm perpendicularly. Do the same for the molecule-ion the instant after the electron has been excited into the antibonding LCAO-MO.
