Atomic Spectra and the Bohr Theory  Ed Vitz, John W. Moore
A section of ChemPrime, the Chemical Educations Digital Library's free General Chemistry textbook.
Atomic Spectroscopy
The Balmer Series  
This animation briefly introduces the basics of the emission spectra of one-electron atoms and ions. The first four lines of the Balmer series can be highlighted and the wavelengths read. There is a link to an Excel spreadsheet, Bohr1.xls, that explores these spectra in more detail.

Atomic Spectra  William F. Coleman
In this Flash animation the user can view the atomic emission spectra (400-700nm) of eight different elements. A dragable marker allows the user to approximate the wavelength of the various spectral lines. The effect of resolution can be examined in the sodium spectrum in the region 550-600nm.

Bohr Hydrogen Atom Emission Series  William F. Coleman
In this Excel spreadsheet students use interactive arrows to explore various series in the hydrogen spectrum. The arrows change the final quantum state of the series. A second tab opens a sheet that allows exploration of the spectra of other one-electron species, by varying the nuclear charge. The nuclear charge is entered and the arrows again control the final state of the spectral series.

General Chemistry Multimedia Problems  David M. Whisnant
General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
