An oxygen molecule (O2) vibrates with an energy identical to that of a single particle of mass

m = 1.340 × 10-26 kg attached to a spring with a force constant of k = 1215 N / m. The energy levels of the system are uniformly spaced, as indicated in FIGURE 30-25, with a separation given by hƒ.

(a) What is the vibration frequency of this molecule?

(b) How much energy must be added to the molecule to excite it from one energy level to the next higher level?
