Bond Length differences between FULL (all electrons correlated) and FROZEN core

Such as MP2=Frozen and MP2=Full
17 10 27 16 27

For GeCl atoms 1 and 2

For GeCl (Germanium monochloride)
Bond length differences (full - frozen) in Å. Mouse over a difference for the bond length with full correlation.
