1- Octene infrared spectrum

Analysis of the infrared spectra of octene hydrogenation products showed that double bond and skeletal isomerization of unreacted olefin takes place. Comparing the spectrum of pure octene-1 (Fig. 2) with the spectrum of the product from Experiment 1 (Fig. 3), it can be seen that the adsorption peak at 1800 cm. i decreases and the doublet at 900 and 980 cm. i is replaced by a peak at 980 cm. which formerly appeared as a shoulder on the 980 band.
