Introduction to Transition State Calculation
Transition state theory is fundamental to the field of chemistry, providing insights into how and why chemical reactions occur. The transition state represents a unique configuration where reactants transform into products, characterized by high energy and instability. Understanding these states is crucial for predicting reaction rates, designing new catalysts, and enhancing product yields in various chemical processes.

Our Service
At CD ComputaBio, we aim to empower researchers and industries with precise transition state calculations, ensuring they can make informed decisions based on reliable data.
Transition State Structure Determination
We use advanced computational algorithms to determine the three-dimensional structure of transition states. Our service can handle complex reaction systems, including multi-step reactions and reactions involving large molecules. We take into account factors such as bond lengths, bond angles, and torsional angles to accurately predict the structure of the transition state.
Energy Profile Calculation
We calculate the energy profile of a reaction, which includes the energies of the reactants, the transition state, and the products. This energy profile is presented graphically, allowing researchers to easily identify the energy barriers associated with the reaction. Our energy profile calculations are based on accurate quantum mechanical methods.
Reaction Rate Constant Prediction
Using the calculated transition state energy and other relevant parameters, we predict the reaction rate constant. Our prediction is based on the Eyring equation and other rate theories, which have been widely validated in the field of chemical kinetics.
Reaction Pathway Analysis
We analyze the reaction pathway by exploring the potential energy surface around the transition state. This includes identifying possible intermediate states and side reactions. Our reaction pathway analysis helps researchers understand the overall reaction process and avoid unwanted side reactions in their experiments.
