I'd like to have something like this, but for single atoms and with more extended range of wavelengths.
All I could find e.g. for hydrogen was lots of talks about Rydberg formula etc. and plots of spectrum in visible region. But I need experimental data to look at, not something plotted from formulas like Rydberg's one.
Similarly for other elements, I mostly found only plots of spectral lines in visible range.
So, where can one find detailed measured spectra for all (or most) chemical elements, preferably with UV and IR parts? It'd be most useful to have it in numeric form (spreadsheet etc.) instead of pictures.
