T / K 300
Level of theory M06-2X/AVTZ
Convolution FWHM / meV 18.6
0-0 transition / eV 9.51
Comments simulation shifted to higher energies by 0.17 eV to match the experimental spectra. The Duschinsky effect was considered using recursive formulae already implemented in the Gaussian09 software package.
