Entropy and the Shelf Model: A Quantum Physical Approach to a Physical Property  Arnd H. Jungermann
A quantum physical approach relying on energy quantization leads to three simple rules which are the key to understanding the physical property described by molar entropy values.

Semiempirical and DFT Investigations of the Dissociation of Alkyl Halides  Jack R. Waas
Enthalpy changes corresponding to the gas phase heats of dissociation of 12 organic halides were calculated using two semiempirical methods, the HartreeĀFock method, and two DFT methods. All five methods agreed generally with the expected empirically known trends in the dissociation of alkyl halides.

On the boiling points of the alkyl halides  Correla, John
Most textbooks spend some time discussing the relationship between boiling point and molecular structure, however, their reasons behind this relationship differ. This variation among textbooks warrants further investigation and discussion in order to uncover which of the factors are the major contributors to the variation of boiling point.
