Instructions

Each reaction for which computational results are available for this model chemistry is plotted below as error in kcal/mol with respect to the benchmark value. Overbound are negative values on the left, and underbound are positive values on the right. Run the mouse over the graph to identify individual points and click on the mouseover link for more information about the reaction.

Set download file formats above labeled as seen. Use comparison tab to generate unlabeled.
