Nettet1. nov. 2016 · There are two intense peaks in the spectrum of 1-octene at low wavenumbers, collectively labeled C in Figure 2. These two peaks are from out-of-plane C-H bending vibrations, or wags as I like to call them. Like aromatic rings, C=C bonds are planar and the C-H bonds fall in the plane defined by the double bond. Nettet31. jan. 2024 · The infrared spectrum was measured in the range of 4000~400 cm −1 using the KBr disk method by a Nicolet 7199B Fourier Transform Infrared Spectrometer. Using a Cary-300 VARIAN, the UV-vis absorption spectrum of the complex was measured by 1 × 10 −4 mol/L DMSO solution. team mancuso south
