Ir peak bonds
WebDec 21, 2015 · Infrared is a powerful identification tool for functional groups because of the similar absorption frequencies for those groups in different molecules. The actual frequency is affected by the environment, … WebIn the last spectrum, I wonder why two peaks at ~3100 cm-1 and 2900 - 2800 cm-1 have the very small intensity. I expect that those peaks belong to C = C bond and C (sp3) - H but it's …
