Mean Amplitudes of Vibration and Thermodynamic Functions of Aluminum Suboxide

A brief vibrational analysis of aluminum suboxide, Al2O, possessing a bent symmetrical structure with the symmetry point group C2v has been made. The computed numerical values of (a) mean‐square amplitude quantities, (b) generalized mean‐square amplitude quantities (mean‐square parallel amplitudes, mean‐square perpendicular amplitudes and mean cross products) and (c) mean amplitudes of vibration for the bonded as well as nonbonded atom pairs at the temperatures T=0 and T=298° K are reported. Discussion of the results is made. The calculated values of the statistical thermodynamic functions on the basis of a rigid rotator, harmonic oscillator model for the temperature range 100‐2000°K are also given.
