Spectroscopic-(adj)relating or having to do with spectroscopy(science that has to do with the emission of light).

Line from Book( page 44):"Instead of rambling, this party had preserved a dignified homogeneity, and assumed to itself the function of representing the staid nobility of the country-side-East Egg condescending to West Egg, and carefully on guard against its //**spectroscopic**// gayety."

My Sentence: This science experiment has to do with spectroscopic matter.
