The Department of Chemistry, College of Education for Pure Sciences has a UV and Visible Spectroscopy device

Electron spectroscopy is one of the types of spectroscopic studies that depend on the absorption of ultraviolet or visible rays. The molecule that absorbs these rays, and the device has provided many measurements for graduate students and researchers, and below are the most important absorption areas for some compounds in the visible region Violet: 400 - 420 nm

Indigo: 420 - 440 nm

Blue: 440 - 490 nm

Green: 490 - 570 nm

Yellow: 570 - 585 nm

Orange: 585 - 620 nm

Red: 620 - 780 nm
