| Description |
The latest and most accurate values of physical constants are stored in Gaussian 98 for conversion between internal quantities (in atomic units) and more common units. Between the releases of Gaussian 86 and Gaussian 88, the best estimates of several of these constants changed more than had been previously expected. Refer to the inside back cover of the manual for the values currently used by default.
In order to facilitate reproducing values produced with earlier versions of the program, the OldConstants keyword requests the values of physical constants used in Gaussian 86. Note that OldConstants should not be used for any other purpose.
NewConstants is the opposite to OldConstants and is the default. OldPhyCon is a synonym for OldConstants, and NewPhyCon is a synonym for NewConstants.
