Dehydrogenation energy of the additives enhancing the photochromism of tungstic acid

摘要

The photochromism in tungstic acid is improved by addition of some organic materi- als. In authors' previous experimental results suggest that the improvement originates in plentiful supply of protons from the additives that are indispensable to the photochromism. By using a semi- empirical molecular orbital method, the dehydrogenation energy of some additives that enhance the photochromism is calculated.
