WebIR of spectrum ethene (double bond), C 2 H 4 [also called “ethylene”] Vs. ethane C2H6 The IR spectrum of ethene is rather uncomplicated due to its simple structure. It has a strong band at 900 cm-1 (11 µm) due to H -C-H out- of-plane wagging. [ out-of-plane bending is usually lower than in- plane bending) WebFT-IR spectra of the gaseous pyrolysis products of raw, unvulcanized, and vulcanized EPDM are shown in Figure 3.The absorptions detected in the gaseous pyrolyzates of the raw EPDM FT-IR spectrum ...

WebFor example, the most characteristic absorption band in the spectrum of 2-hexanone (Figure 6.3a) is that from the stretching vibration of carbonyl double bond C=O at 1716 cm-1. It is a very strong band comparing to the others on the spectrum. A strong absorbance band in the 1650–1750 cm-1 region indicates that a carbonyl group (C=O) is present.
