Hello Marlido,
There is a website with several reference spectra, including images. The
address is:
http://www.hq.eso.org/lasilla/Telescopes/2p2T/E1p5M/memos_notes/Line-atlas-int.h
tml
If that doesn't work, university libraries should have reference books
with spectra in the appropriate region.
Thanks for writing,
Kurtis Williams
