22-15 |
Spacing, etc., between energy levels of an ideal gas as described by the model of a particle in a 3D box. The upper limit of 3kT for the energy has been chosen as twice the average energy. Most molecules will have energies below 3kT. |

22-17 |
Assume that the vibration of an N2(g) molecule can be described well by the harmonic-oscillator model. What then is the ratio of numbers of molecules in the v=1 state to molecules in the v=0 state at several different temperatures? Spectroscopist can measure such a ratio to determine the temperature of a gas. |

A problem similar to 22-17 but this time rotational energy levels, which are much closer together than vibrational energy levels, are considered. The problem assumes that the rigid rotor is a good model, which is true if J is not large. |

Some additional, and quite short, problems on the same subject. |
