Debye Theory of Solids

In solid-state physics, debye theory is used to estimate the phonons contributing to the specific heat capacity in a solid. It explains that the specific heat is a consequence of the vibrations of the atomic lattice of the solid, which is in contrast to the Einstein model. In the Einstein model, solids are treated as independent, non-interacting quantum harmonic oscillators. This model clearly explains the low-temperature dependence of the heat capacity, which is proportional to T3. This is known as Debye T3 law.

The measured density of a KCl crystal is 1.984 g/cm3. What is the equilibrium separation distance of K+ and Cl- ions?
To give a helium atom nonzero angular momentum requires about 21.2 eV of energy (that is, 21.2 eV is the difference between the energies of the lowest-energy or ground state and the lowest-energy state with angular momentum). The electron-volt or eV is defined as 1.601019 J. Find the temperature T where this amount of energy equals kTB/2 . Does this explain why we can ignore the rotational energy of helium for most purposes? (The results for other monatomic gases, and for diatomic gases rotating around the axis connecting the two atoms, have comparable orders of magnitude.)
A gas phase H19F molecule has a bond length of 91.68 pm and a vibrational force constant,k = 966 N/m. For the v = 0, J = 10 and v = 1, J = 10 rovibrational levels, calculate the period of rotation andvibration. How many times does the molecule rotate during one vibrational period?

The probability of finding an N2 molecule at ambient temperature at 515 m/s is zero. True or False?
Although an ordinary H2 molecule consists of two identical atoms, this is not the case for the molecule HD, with one atom of deuterium (Le., heavy hydrogen, 2H). Because of its small moment of inertia, the HD molecule has a relatively large value of E: 0.0057 eV. At approximately what temperature would you expect the rotational heat capacity of a gas of HD molecules to "freeze out," that is, to fall significantly below the constant value predicted by the equipartition theorem?
A CO molecule is initially in the n = 2 vibrational level. If this molecule loses both vibrational and rotational energy and emits a photon, what are the photon wavelength and frequency if the initial angular momentum quantum number is l = 3?
The fundamental frequency is 2230 cm−1 for the molecule 1H127I. If the H atom is replacedwith D (an isotope of H atom with mass 2, i.e. 2H), calculate the fundamental frequency assumingthat the force constant stays the same. Repeat the calculation if the diatomic molecule underconsideration is 1H37Cl (fundamental frequency = 2886 cm−1). Explain your observations.
