At a given temperature the rotational states of molecules are distributed according to the Boltzmann distribution. Of the hydrogen molecules in the ground state estimate the ratio of the number in the ground rotational state to the number in the first excited rotational state at 300 K. Take the interatomic distance as 1.06 Å. Estimate the wavelength of radiation emitted from adjacent vibration energy levels of NO molecule. Assume the force constant...

Problem 5: This problem deals with gases used for a He-Ne laser. Consider the Neon transition at 632.8 nm. The upper level of the transition (with respect to ground level of Neon) coincides with a 2s level of Helium that has the energy of 20 eV with respect to the ground level of Helium. The gases are kept at room temperature (300K). We consider only three different energy levels of Neon: ground level, lower level of the laser transition, and...

(2) Cyclohexane (CH) has two conformations, i.e. the chair conformation (e) and boat conformation (b). At 298 °K, the chair conformation (e) is at the ground state with energy = 0; and the boat conformation (b) is at the energy level of 22,000 J/ mol. (i) Calculate the molecular partition function (q) of cyclohexane at 298 ®K. (ii) Calculate the Boltzmann distribution (the most probable distribution) of the two conformations, and respectively. (iii) Compare these two conformations, which conformation is...

2. Interacting Spins (5 points each part, 30 points total). Two spins, each of which can be in one of two states, up or down, are in equilibrium with a heat reservoir at temperature t. They interact as follows: When the two spins point in the same direction, their interaction energy is – J, and when they point in opposite directions, their interaction energy is J. The spins also each have a magnetic moment m and are subject to a...
