WebThe spectrum of nearly all solar electromagnetic radiation striking the Earth's atmosphere spans a range of 100 nm to about 1 mm (1,000,000 nm). [citation needed] This band of significant radiation power can be divided into five regions in increasing order of wavelengths: [17] Ultraviolet C or (UVC) range, which spans a range of 100 to 280 nm. WebOn our IR spectrum, it occurred at 2902.90 cm -1 to 3090.58 cm -1, with the largest peak at 3018.05 cm -1. The carbonyl peak occurs between 1650 cm -1 to 1750 cm -1 and the alcohol peak occurs at about 3600 cm -1. Our product had the C=O bond, and therefore it did indeed show up on the IR spectrum at 1656.21 cm -1.
