- disperse separate (light) into spectral rays
- chromatic able to refract light without spectral color separation
- spectrograph a spectroscope by which spectra can be photographed
- spectroscopy the use of spectroscopes to analyze spectra
- prismatic exhibiting spectral colors formed by refraction of light through a prism
- spectrometry the use of spectroscopes to analyze spectra
- spectrum analysis the use of spectroscopes to analyze spectra
- spectrographic analysis the use of spectroscopes to analyze spectra
- hyperfine extremely fine or thin, as in a spectral line split into two or more components
- red shift (astronomy) a shift in the spectra of very distant galaxies toward longer wavelengths (toward the red end of the spectrum); generally interpreted as evidence that the universe is expanding
