The simple mass on a spring is the basis for our description of almost any oscillation. Let’s consider the vibrational states of a simple diatomic molecule, say N2. We will model it as two identical masses connected by a spring as shown in the figure at the top right.This is a little different from the cart on a spring since there is no wall -- both of the atoms are moving. But if we only look at oscillations of the molecule where the center of mass is not moving, the atoms are moving equally and oppositely. When one is going left, the other goes an equal amount to the right and vice versa. This is like two carts attached to a wall and oscillating equally and oppositely as shown in the lower picture. The only difference is the way we treat the spring. When each atom moves a distance x, the spring between the atoms actually stretches a distance 2x, so the force on each atom is -2kx. We can therefore model the motion of one of the nitrogen atoms as a single “cart on a spring” if we…
Are all energy levels equally spaced with respect to n? If not, do they become more or less closely spaced as n increases?   Draw a new figure of 4 horizontal lines where each horizontal line corresponds to one energy level. Place the horizontal lines vertically to scale such that they are spaced accurately according to their energy, and label your lines corresponding to n=1, n=2, etc.   Using this diagram, identify the largest energy transition between two adjacent energy levels. Calculate this energy difference and the corresponding frequency and wavelength of the emitted photon. Identify the largest energy transition that can occur between any two levels in your diagram. Calculate the energy for this transition along with the corresponding wavelength of the emitted photon.
