Free interactive chemistry · GUIDE-MECH
Mechanism player
Step through a reaction mechanism in 3D with curved arrows and an energy profile.
Open the interactive simulation →How to use this simulation
- Choose a mechanism from the list.
- Press “Play whole mechanism”, or use “Next step” and “Previous step”.
- Drag the “Reaction progress” slider to scrub back and forth.
- Read the steps, “Facts” and the energy profile.
What to notice
- A curved arrow’s tail shows where an electron pair starts; its head shows where it goes.
- Each hump on the profile is a transition state; each valley between humps is an intermediate.
