====== Physical constants ======

The values of fundamental physical constants are revised periodically by CODATA. Molpro uses the values from the latest revision. Some previous values are available, see the ''%%lib/include/codata/%%'' directory. To use these system include files, simply add for instance:

<code>
include,codata/molpro2006
</code>
to use the values from Molpro 2006.
