Visualisation of Transition Densities

[Tackley Daniel R <Daniel.Tackley<<at>>avecia.com>]

Hi,
 In Gaussian 98 I had a method of visualising transition densities (ground to
 excited state) obtained from a TDDFT calculation - this involved a series of
 jobs which read the excited state electron densities from the checkpoint
 file and generated cubes file using the CUBE keyword. I also generated a
 cube of the ground state electron density and then did some cube
 subtractions. I know that this may not have been the best way to do it but
 it was sufficient for my needs.
 In Gaussian 03, the CUBE keyword has been depreciated in favour of the
 cubegen utility so I was wondering what the best way of visualising the
 transition densities is. I have tried using Density(Transition=1) in the
 route section of the job but can't find any way of generating a cube file of
 this density.
 Any hints on a suitable job files for achieving the following would be most
 appreciated:
 Generate a cube file for each excited state of interest from a TDDFT
 calculation which contains the transition density between the ground state
 and that excited state.
 Thanks for your help,
 Daniel Tackley
