I am trying to calibrate a ND6000 dye laser using an Fe cathode Ne gas hollow cathode lamp. However, I am having difficulty in confirming my spectral assignment of optogalvanic lines with NIST Standards. I would like to know if anyone has an Fe/Ne optogalvanic spectrum and line assignments for the region 498.7 to 512.8nm (19500-20050 cm-1).
