Consider the Hamiltonian of a particle in one-dimensional problem defined by: H = 1 2m P 2 + V (X) where X and P are the position and linear momentum operators, and they satisfy the commutation relation: [X, P] = i¯h The eigenvectors of H are denoted by |φn >; where n is a discrete index H|φn >= En|φn > (a) Show that < φn|P|φm >= α < φn|X|φm > and find α. Hint: Consider the commutator [X, H] (b)...

If we replace one of the carbon atoms (and its associated H atom) in benzene by a nitrogen atom, we obtain the molecule pyridine which is also an aromatic six membered ring. Sketch a qualitative MO diagram for pyridine and describe how you expect the energy levels of pyridine to differ from those of benzene.

Use Bohr's model of the H atom to explain the origin and the characteristics of X-rays.

3) A hydrogen atom contains just one electron, so it can produce only one wavelength of light (and therefore only one color of light) at a time. Why then do we see many different colors of light simultaneously when we observe the emission spectrum of hydrogen?
