NIST Atomic Spectra Database Lines Form

Specify search criteria to display spectral lines. For spectra of the elements H-Ni, multiplet-ordered data is available. To obtain data in multiplet-ordered form, specify one spectrum (leaving "Central Wavelength" and "range" blank), select "Set Output Preferences" below, and then on the page that comes up select "Only lines with transition probability data" in the Output Options Interest category.
Spectra:	e.g. Fe I or Na, Mg , Al  or mg i-iii
	Or, select spectra from the List of Holdings, or select spectra using a selection form, or choose All Spectra.
