[Example] MaterialsStudio Transition State Exploration
[Example] We will guide you through the exploration of transition states using LST/QST.
◇Transition State Exploration Using LST/QST: Case Study - To explore the potential energy surface of a chemical reaction, information regarding structural, energetic, and kinetic aspects for each step of the reaction process is necessary. - Among that information, finding the transition state is particularly important. - In this case study, we analyze using LST and QST, which are well-known methods for transition state exploration, in Materials Studio. 【Product Features】 ■ Also ideal for "Materials Informatics" ■ Simulation software that streamlines material development Available for use by those engaged in research, development, design, and manufacturing across various industries ■ Helps in the development of new materials more efficiently and easily. ■ Compatible with various types of materials ■ All operations, including crystal structure creation, calculation condition settings, and calculation result display, can be performed on a single GUI screen. *For more details, please feel free to contact us.

◇Transition State Exploration Using LST/QST (Overview) - To explore the potential energy surface of a chemical reaction, information regarding structural, energetic, and kinetic aspects for each step of the reaction process is necessary. - Among that information, finding the transition state is particularly important. - In this case, we are analyzing using LST and QST, which are well-known methods for transition state exploration, in "Materials Studio."
-
◇Calculation Model and Methods 221_4 - Vinyl alcohol was used as the reactant, and acetaldehyde was used as the product in the calculation model. - Additionally, by using LST to linearly interpolate the reaction pathway from the reactants and products, we created the reaction pathway. - By combining this reaction pathway with QST, we will conduct a transition state search. - For the structural optimization of the model and the transition state search, we used the DMol3 module, which can handle a wide range of computational targets in quantum mechanical calculations.
-
◇Discussion of the Required Physical Property Values - The diagram shows the flow of transition state analysis. - First, by combining the linear reaction pathway obtained from LST with QST, we explore and plot the reaction pathway. - Next, we analyze the spectrum from the results and visualize the molecular movements related to the peaks of the imaginary frequencies. - In the visualized molecule, it can be seen that as hydrogen moves, the bond order also changes.
