A sample cell and delivery system for rapid matrix isolation of gas mixtures at constant gas temperature was designed and evaluated. The rotational energy differences of 1,2-dichlorosthane and of its deuterium compound wars then determined to test this technique.

The rotational energy barriers calculated from Boltzman plots of ths gases at different temperatures were; 1.21 + 0.38 keel/mole, 1.33 + 0.70 Real/mole, and 1.12 + 0.45 kcal/mole for the CH2 wagging„ C-Cl stretching and CD2 wagging modes respectively. These values were in good agreement with previously published values.

These results allowed evaluation of this apparatus and experimental design and suggested areas for possible improvement. The results also showed the value of rapid matrix isolation in the determination of rotational energy barriers in small molecules such as 1,2-dichlorosthans.
