Dynamic Transformation of Chemical Reactions of M + YX → [MYX] → [MXY] → MX + Y — •Victor Wei-Keh Wu — Department of Electronic Engineering, Lan-Yang Institute of Technology, 261-02 Tou-Cheng, I-Lan, Taiwan, Republic of China
It has been for ca. 80 years that chemical reaction dynamics in general form of A + BC → AB + C has been investigated. In the mean time, it can be well concluded: M + YX = M + HX/CH3X/DX → [MYX] → [MXY] → MX + H/CH3/D = MX + Y : the more heavier of M (M = Ba, K) of the reaction Ba/K + HBr, the less possible that H firstly attaches M, or the more heavier of Y of Ba + HBr/CH3Br (Y = H, CH3, D), the less possible that Y firstly attaches M, before MX is produced. This means there is more or less migration, coordination of relative positions of involved atoms during the moment of colliding or sticking together of all atoms. The energy and momenta (translational, orbital and angular) along the whole reaction route must be naturally conserved. How far whether L + J = L’ + J’ can be approximately treated with L ≈ J’ should also be kept investigated. These trends may be extended for the biomolecular reaction dynamics, specifically, for the interacting atoms of the respective functional groups of the respective sites of interacting biomolecules. To confront with these subjects, many assumptions and simplifications for simulation must be done. The author is at the same time in charge of Victor Basic Research Laboratory e.
