WebJul 1, 2024 · The peak labeled A at 2917 cm-1 is the methylene asymmetric stretch, the peak labeled B at 2852 is the symmetric stretch, and the peak labeled D at 718 is the rock. Recall that the 720 peak only appears if there are four or more methylenes in a row (6), which is true of probably every polyethylene molecule. WebI found out that a broad/wide peak at 3428.90 cm-1 for 300 0 C and the peak tends to linearity at 400 0 C. Also I have found a broad and blunt peak at 1099.43 cm -1 for 300 0 C …
WebThe region of the infrared spectrum from 1200 to 700 cm-1 is called the fingerprint region. This region is notable for the large number of infrared bands that are found there. Many different vibrations, including C-O, C-C and C-N single bond stretches, C-H bending vibrations, and some bands due to benzene rings are found in this region. WebJun 28, 2016 · What matters is what the peaks look like. In other words: how strong/weak they are how narrow/wide they are where they are horizontally (their vibrational frequency) because that's how you identify which bond stretches or bends those rotational or vibrational peaks correspond to.
