Application of Angular Momentum Conservation Law in Chemistry

Based on the first principle of global angular momentum conservation, this paper systematically explains the fundamental unifying role of this core physical law in the whole field of chemistry, covering core branches including atomic structure, chemical bond, stereochemistry, chemical reaction kinetics, catalytic chemistry and coordination chemistry. It reveals the angular momentum dynamic origin of various chemical phenomena, breaks the theoretical barriers between physics and chemistry, reconstructs the underlying logic of basic chemical theory, and provides a unified theoretical framework for the essential interpretation of chemical phenomena, reaction regulation and chiral synthesis.
