✦ Synopsis

The c%emilumincscence spectrum of the reaction Ba + CCL has been anaIyzed to be due to x-z emission of CC12.

Since the x state is known to have a long lifetime (3.8 PS) it is possible to determine the angular distribution of the chemiIuminescent species visually. In addition, the mean translational energy, E'ms, of the product molecules can be estima&L Within the experimental accuracy the angukxr distribution is nearIy isotropic and ,!?u has been estimated t3 be on the order of 0.4 eV. The chemiluminescent cross section is approximately three orders of maztitude smaller than the mrrin reaction channel leading to B&I(X) + CCl3.

## Abstract The radical‐molecule reaction mechanism of CHCl~2~ and CCl~3~ with NO~2~ have been explored theoretically at the B3LYP/6‐311G(d,p) and MC‐QCISD (single‐point) levels. For the singlet potential energy surface (PES) of CHCl~2~ + NO~2~ reaction, the association of CHCl~2~ with NO~2~ was fo
