Abstract:

AN investigation of transients in cyclobutene vibrational relaxation by the VEM method has been made. Temperatures in the region 429 K to 778 K were used. Cyclobutene molecules isomerize to butadiene when transported above the critical threshold E sub 0. The collision efficiency of the wall increases with lowering of temperature, and strong collider behavior is obtained below 450 K. The data are described by a gaussian form of the collisional transition probability function. An exponential form of the probability function cannot fit all of the data. Author
