As shown in the header image, a prism is able to separate the wavelengths of light that make up a beam of white light. Thus, white light consists of a spectrum of colors. The wavelengths we are able to see with our eyes are called the optical spectrum. I have a PhD in Chemical Physics. My research thesis had to do with the optical spectra of transition metals in crystals. By analyzing the specific wavelengths of light absorbed by a particular metal ion, one is able to determine the geometry in which the ion is situated, assuming, of course that someone has studied those spectra in which the metal ion is in known geometries. That was the purpose of my research, so spectra are somewhat special to me.

Basic Audio Technology and Electronics

With a few items of personal interest thrown in for variety.

I try to keep the information here up to date.

Some updates may happen in the main body of the pages,

but most are done in the Blog and in Resources and Tutorials links.

If these subjects interest you, check back from time to time for updates.
