Basis set selection

Many of the pages in the CCCBDB display results as several tables with different rows for different methods and different columns for different basis sets.
Calculated results will be displayed for the following basis sets. You may omit some basis sets. The "small", "medium", and "large" designations are somewhat arbitrary. Check or uncheck the boxes to include or exclude certain basis sets. Click the boxes to the right to include or exclude classes of basis sets.
Also see the pages for selecting method categories.
