Molecular Rocket and Implantation Reactions: Shock-Induced Phenomena at Atomic and Molecular Levels

Molecular rocket reactions are unique but contain important features. This paper deals with their relation to shock-induced phenomena. Extraction of metallocene from a cavity of cyclodextrin is assisted by shock of collision and is followed by rearrangement reactions. Severeness of the rearrangement depends on energy. Collisions of implanted atoms also extract metallocene molecules from inclusion compounds to cause rearrangement reactions. This is ascribed to a shock-induced phenomenon. Collision cascade enhancement of the yield in implantation reaction is closely related to shock waves generated after the implanted atom. Forward pressure pushes the implanted atom and reactant molecules into the microcrack formed in implantation in metal β-diketonates. In the case of metallocene implantation, however, another mechanism involving an increased number of replacement paths should be considered.
