Outline of Final Research Achievements

In the present study, the following 2 investigations have been conducted.
1. In order to facilitate in situ X-ray crystallographic analysis, a novel crystal mount equipped with a glass capillary and a custom-made valve has been devised in the present study. It was found that the newly developed crystal mount could keep the internal gas pressure up to about 5 atm.
2. Gas adsorption states of organic crystals prepared in the present study have been analyzed at an atomic level by using the novel crystal mount mentioned above. Theoretical calculations for the gas adsorption state were carried out to disclose the mechanism of the observed gas adsorption behavior.
