This absorption overlaps the sharper C-H stretching peaks, which may be seen extending beyond the O-H envelope at 2990, 2950 and 2870 cm -1. The smaller peaks protruding near 2655 and 2560 are characteristic of the dimer.

WebNov 9, 2024 · At first glance, the IR spectra look very complicated, but the only three things you need to know are: regions of the spectrum, one number (1500), and location and shape of the peaks. Let’ s considers all of these. IR spectra can be divided into two main regions: Diagnostic region – generally has fewer peaks and provides the clearest information. WebNotice how strong this peak is, relative to the others on the spectrum: a strong peak in the 1650-1750 cm-1 region is a dead giveaway for the presence of a carbonyl group. Within that range, carboxylic acids, esters, ketones, and aldehydes tend to absorb in the shorter wavelength end (1700-1750 cm-1), while conjugated unsaturated ketones and ... party rentals hyattsville md
