CHN and its cousin FULLCHN are powerful tools for finding transition states. Unlike standard geomtry optimizers, this method is useful for finding the specific transition state(s) between a specified reactant and product. (See Chapter 8, CHN Methods for more details.) For this example, we consider three-fold dissociation of triazine into three separate HCN molecules. (This reaction is sometimes referred to as the “triple whammy” reaction.) By inputing the two end points, CHN is able to locate the corresponding transition state.

The first geometry corresponds to left end point geometry. |
|
The field "FOR REACTION COORDINATE" specifies the position along the reaction coordinate of the geometry. The left geometry corresponds to a reaction coordinate value of 0.000 Å. |
|
This geometry corresponds to the transition state and is identified as having 1 accurate unstable mode. |
|
The final geometry corresponds to the right end point geometry. It is located at 4.888 Å along the reaction coordinate. |

Information on the criteria that chain will use is listed in this section of the output. |
|
OPTIL requests that the left endpoint is optimized. In this case, it is already a minima so nothing needs to be done. |
|
OPTIR requests that the right endpoint is to be optimized. The energy and RMS gradient of the optimized structure is reported here. |
|
A summary of the entire chain is presented here in the output file. Each node on the chain is characterized by its heat of formation (relative to the left end point), the RMS gradient, and a characterization of the type of geometry. This is useful for getting a quick overview of the entire chain. |
|
The heat of formation and other properties of the transition state. |
