This is a reference and resource webpage for the spectroscopy workshop given by John C. Martin at the Society of Astronomical Sciences meeting on May 22, 2012. I have continued to maintain it as a general resource for non-professional astronomical spectroscopy.
Here is a full-color copy of the slides presented at the workshop.
Alex Filippenko's paper on differential atmospheric refraction.
Java applet demonstrating Kirchoff's Laws of Light and Matter.
Teaching tool for learning about the concept of Doppler shift.
Recommended book on spectral classification: The MK Process by Morgan
Rainy Day Spectroscopy (favorite free access online spectra archives)
