The Heat Capacityof Al(OH)<sub>3</sub> Revisited

We consider different approximations to compute the heat capacity for Al(OH)<sub>3</sub> and compare the computed results to the experiment. We find that the calculation of anharmonic effects for this molecule is not currently practical, and scaled harmonics, using the scaling factor for H<sub>2</sub>O(g), offer the best approach to including anharmonic effects. The Pitzer–Gwinn approach for hindered rotations is recommended.

Abstract

We consider different approximations to compute the heat capacity for Al(OH)<sub>3</sub> and compare the computed results to the experiment. We find that the calculation of anharmonic effects for this molecule is not currently practical, and scaled harmonics, using the scaling factor for H<sub>2</sub>O(g), offer the best approach to including anharmonic effects. The Pitzer–Gwinn approach for hindered rotations is recommended.
