[molpro-user] question about energy scale

[Yusuke Nakagawa]

 Dear molpro user,

 I'm challenging to calculate the bond length - energy curve of dimer  with bond length being some nm scale, but using the 'merge' command, the curve is calculated to be flat.
 I want to call into account long range interaction between two atoms,
and display the results more minutely.

 Is there any command which calculates the long range interaction such as dipole-dipole interaction?  Can the result be displayed to the order of 10^(-10) or under? 

 Thank you in advance.
