System Documentation

What problem does it solve?

This Skill optimizes a molecular transition-state (TS) geometry from an initial guess and validates that it is a first-order saddle point using vibrational analysis.

Core Features & Use Cases

  • TS optimization for non-periodic molecules: Runs Sella-based TS optimization followed by a finite-difference vibrational frequency check.
  • First-order saddle validation: Classifies the optimized structure by counting imaginary modes below a configurable cm^-1 cutoff.
  • Backend-ready execution: Supports MLIP backends for scoring/optimization (MACE or FAIRChem/UMA) and writes a complete results bundle.

Quick Start

Use the chem-ts-optimization Skill to optimize a TS guess for a non-periodic molecule and confirm first-order saddle character by generating ts_optimized.xyz and ts_optimization_results.json from a provided ts_guess.xyz file.
