I'm trying to get the spectral analysis data of the periodic table of elements in the time domain format or find a site that has the data in the time domain format. All the sites I know have the data in the frequency domain which is great but I need to do my own fft analysis starting from the time domain because the frequency domain does not include the phase angle data, which I also need to use for my calculations/animations.
Does anyone know where I can get this data or can someone send me the spectral analysis data for sodium and potassium in the time domain?
Thanks
