IRC

An Intrinsic Reaction Coordinate calculation is to be run. All kinetic energy is shed at every point in the calculation. See Dynamic and Intrinsic Reaction Coordinates for more details.

By default, steps of 0.05Angstroms are used. This default can be changed using keywords:

To print reaction coordinate steps that are separated by constant energy, use H-PRIORITY or H-PRIORITY=n.nn.
To print reaction coordinate steps that are separated by constant distance, use X-PRIORITY or X-PRIORITY=n.nn.

Use LARGE to control print of internal coordinates and Cartesian coordinates.
