Orca transition state optimization
WebRun a Transition State Geometry with the keyword OPTCYCLE=5 (or some small number). This job will (most likely) run out of optimization cycles. Go back to step 1 to get the real/exact hessian and repeat. If at any point in step 2 you discover that there is no longer a good negative eigenvalue you need to adjust the geometry.
