Spectra of Arsenic (As)

The following images are color coded spectrum of arsenic undergoing flame or 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 it's element emission line file and computes the spectra...

Arsenic Flame Spectrum

Here is a lower quality jpeg of the spectra:


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

Arsenic Spark Spectrum

Here is a lower quality jpeg of the spectra:

The spectra are calculated to represent the emission from a flame or a spark source and are based on the work of John Talbot. Additional data for each element were obtained from the National Institute of Standards and Technology.
