dc.description.abstract We have used time-resolved infrared/mm-wave double resonance techniques to study the temperature dependence of rotational and vibrational collisional processes in methyl chloride. Previously, these processes have been studied in detail at room $temperature^{1}$. Of particular interest is the K-changing rotational collisional process, which is very thermal in nature. The theory used to explain the room temperature results makes straightforward predictions about the properties of K-changing collisions at other temperatures. The accuracy of these predictions will be discussed. Of more practical interest is the cumulative rate of all collisional processes over this temperature range, which is observed as pressure broadening. We have studied the temperature responses of the collisional processes in $CH_{3}Cl$ that have significant contributions in pressure broadening, including the dipole-dipole process. This information should serve as a guide for understanding the temperature response of pressure broadening in other similar molecules. en_US
