Explain expression for the vibrational heat capacity

Reference no: EM13225458

Molecular solid can be pictured as the collection of independent harmonic oscillators. (a) Starting with the expression for the partition function derive an expression for the vibrational heat capacity, CVvib, for a molecular solid and (b) calculate CVvib (in JK-1mol-1) for solid I2 at 25°C given its vibrational wavenumber of 214.6 cm-1.
