Abstract :
In the chromatographic process, the activation energy of solute migration determined solute migration velocity in the given condition. The rotational energy and vibrational energy of solute strongly influenced the activation energy of solute migration, and it caused the activation energy to change with temperature. These properties of migration activation energy were validated by the calculation of rotational and vibrational energy with statistical thermodynamics and the principle of equipartition of energy. It would be a good method to research molecular movement (translation, rotation, vibration) by means of gas chromatography.
