WebThe absorption bands in IR spectra have different intensities that can usually be referred to as strong (s), medium (m), weak (w), broad and sharp. The intensity of an absorption band depends on the polarity of the bond, and a bond with higher polarity will show a more intense absorption band. WebTranscribed image text: 5. (5 pts) Aldehydes, ketones, and carboxylic acids all have a strong IR peak around 1750 cm-. Using table of IR stretching frequencies provided in the introduction and the structure of each of these compounds, explain why this is so. 6.

Web1), and near-IR spectrum (4000-13000 cm-1). The mid-IR spectrum is the most widely used in the sample analysis, but far- and near-IR spectrum also contribute in providing information about the samples analyzed. This study focused on the analysis of FTIR in the mid-IR spectrum.
