Analyze spectral data with ease. SWizard help you postprocess spectral data. A spectrum is convoluted as a sum of Gaussian, Lorentzian, or pseudo-Voigt functions.
For UV-Vis spectra, the program reads excitation energies and oscillator strengths directly from output files and produces electronic spectra of molecules in the ASCII data format.
For IR/Raman spectra, the program reads the vibrational frequencies and intensities directly from Gaussian or "free-format" files and produces vibrational spectra of molecules in the ASCII data format.
