The only papers that I have read dealing with emission, have calculated a
single value for the energy by calculating the difference between (a) the
energy of the lowest energy excited state and (b) the energy of the ground
state at the geometry of the excited state. As regards software, any general
purpose computational chemistry program such as GAMESS, PC-GAMESS, Gaussian,
ADF, Jaguar could be used.

Since the fluorescence spectra is usually a single peak (?), this seems to
be the simplest method. You could convolute the peak (on an energy scale)
using a Gaussian curve (for example, using Excel) and convert to wavelength.
This would then look like a fluorescence spectrum.

Regards,
Noel O'Boyle.
