Spectra of Barium Gas Discharge

The following image is color coded spectra of barium undergoing electrical discharge excitation.

It is computed and plotted in your browser by a Java program which reads a file containing a list of emission line wavelengths and their corresponding strengths.

Note: This program generates deep 24 bit color plots, therefore you may need to increase the color depth of your system to view subtle details in these spectra.

There may be a small delay as each Applet loads its element emission line file and computes the spectra...


Barium



Both neutral and singly ionized barium contribute to the emission lines in this spectrum.

Strontium Spectra in Two Parts:

from 4000 to 5500 Ångstroms
and from 5500 to 7000 Ångstroms
