I just joined this group to specifically ask a question about spectra.
I am not an amateur astronomer, but an artist who is incredibly fascinated by stellar spectroscopy - particularly its history and use in America in the late 19th and early 20th centuries. I'm working on a project where I need to visualize and reference the absorption or emission spectra of all the elements. I have found a few different sources online for this, but some are incomplete and more maddeningly there are some variations between the sources. In not having an astronomy or chemistry background, I wanted to reach out to people more knowledgeable than I and see if there is a good complete, trusted, and standard reference for the spectra of elements. A book? A site? Anything?
I assume minor variations between the sources to be possibly based on sensitivity (number of visible lines), but I certainly want to make certain that the basic elemental "signature" is correct and I'm not foolishly using spectra that are wildly inaccurate. I've found image files on this website http://www.alexpetty...table-of-light/ and other image files in Wikimedia Commons and would be thrilled if people have other sources, references, or opinions on these sources that they could give me.
Many thanks in advance for any help you can provide.
