ORCA NEB-TS transition-state search to locate and verify minimum energy paths between reactant and product structures, enabling systematic TS discovery and barrier estimation.
Provide reactant and product structures and run an ORCA NEB-TS workflow to locate and verify a transition state along the minimum energy path.

To find an ORCA transition state, you provide both reactant and product structures to run an NEB-TS workflow. The process interpolates images between the two geometries, optimizes the path, and refines it using CI-NEB to locate the transition state.
ORCA NEB-TS is a computational chemistry method that maps a minimum energy path between reactant and product structures. It works by interpolating intermediate images, performing NEB optimization, and refining with CI-NEB to identify the transition state.
To verify a transition state in ORCA, the NEB-TS workflow includes a TS verification step that checks for exactly one imaginary frequency. This confirmation ensures the located geometry is a true transition state along the mapped minimum energy path.
Yes, you strictly need both reactant and product structures to run an ORCA NEB-TS workflow. The transition-state search enforces this requirement to interpolate images and map the minimum energy path between the two endpoints.
The best way to perform CI-NEB refinement is through a reproducible ORCA NEB-TS workflow. After initial image interpolation and NEB optimization, CI-NEB refinement runs to accurately identify the transition state along the minimum energy path.
