COMPARISON OF THE DYNAMICS OF THE REACTIONS OF BA WITH AROMATIC HALIDES AND ALKYL-HALIDES - LIF STUDIES OF THE REACTIONS OF BA WITH C6H5X (X=CL, BR, I)
Nascent internal state energy distributions of BaX have been studied for the reactions Ba+C6H5X --> BaX+C6H5 (X=Cl, Br, I) using the laser-induced fluorescence method in a beam-gas arrangement. The energy disposal differs markedly from that of the reactions Ba+CH3X. With the change of X from Cl to I, the vibrational excitations and the reactive cross sections decrease for the reactions Ba+C6H5X, whereas those of the reactions Ba+CH3X increase. The CNDO/2 calculations of C6H5X and CH3X have been used to interpret the experimental results qualitatively
