Subject: MOPAC Charges ?


Dear CCLers,

MOPAC calculates "NET ATOMIC CHARGES" in a really simple manner: 
atom electron densities are calculated as a sum of the diagonal elements of 
the density matrix, and net atomic charges are then calculated by subtracting
this value from the core charge.
I know, there are much better methods for charge calculation (ESP...), however,
can anybody tell me, whether this method has a special name, or can give me a
literature reference ?

Thank you  

Martin

"LARGE SCALE COMPUTATIONS IN CHEMISTRY: APPLICATIONS TO
		 MATERIAL SCIENCE"

	      10, 11 and 12 June 1996
Department of Physical Chemistry
University of Barcelona 
Barcelona, Spain

The organizing committee of the "6TH INTERNATIONAL CONFERENCE
ON THE THEORETICAL ASPECTS OF HETEROGENOUS CATALYSIS", CAT-96,
is pleased to announce the above workshop as a satellite of
CAT-96. The workshop is organized by the Department of Physical
Chemistry of the University of Barcelona and the Department of
Chemistry of the Rovira i Virgili University and it is possible 
thanks to the help of the "Centre de Supercomputacio de Catalunya"
(CESCA).

The workshop will be held at the Physics Faculty of the University
of Barcelona from Monday to Wednesday, June 10-12 1996, immediately
following the CAT-96 Tarragona meeting on June 2 to 7. 

The workshop is addressed to graduate students with a background
in quantum chemistry, condensed matter physics, or other areas
related to material science. The sessions will consist of a series
of talks of about 50 or 20  minutes followed by an open discussion
of about 10 minutes. Active participation of the students is highly 
encouraged.
