Subject: CCL: dipole and polarizability in MOPAC

Dear all,

I have met some difficult to recognize the value of
dipole (or dipole moment) and polarizability (or
polarizability volume) in the output file of MOPAC
6.0.

I wonder what's the difference between the dipole and
dipole moment, and between the polarizability and
polarizability volume. What's the values given by
MOPAC 6.0? And which values should be reported in
paper?

The section of dipole and polarizability in the output
file of MOPAC 6.0 is appended in the end of this email
as an example.

Thank you very much for your concern on this matter.

Best wishes,

Jinsong
