Ab Initio Potential Energy Surface and Vibration-Rotation Energy Levels of Aluminum Monohydroxide
1Department of Chemistry, Adam Mickiewicz University, 61-614 Poznań, Poland.
Abstract:
The potential energy surface and vibration-rotation energy levels of aluminum monohydroxide in the X̃ 1A' electronic state have been determined from ab initio calculations. The equilibrium configuration of the AlOH molecule was found to be bent, although with a wide AlOH angle of 163° and a small barrier to linearity of just 4 cm-1. The AlOH molecule was definitely confirmed to be quasilinear. The predicted spectroscopic constants of the AlOH, AlOD, 26AlOH, and Al18OH isotopologues can be useful in a future analysis of high-resolution vibration-rotation spectra of these species.

Aldehydes and Ketones with Water: Hydrate Formation
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...
