Automated reaction mechanisms and kinetics with the nudged elastic band method‐based AMK_Mountain and its description of the preliminary alkaline hydrolysis of nitrocellulose monomer
Abstract To improve the transition state (TS) search capability in complex chemical environments, AMK_Mountain is constructed based on the automated reaction mechanisms and kinetics (AutoMeKin) package. AMK_Mountain does not distinguish the reaction type of the TSs, which is beneficial to obtaining...
