We can see in the table that sp3 hybridized C – H bonds in alkanes and cycloalkanes give signal in the upfield region (shielded, low resonance frequency) at the range of 1–2 ppm. The only peak that comes before saturated C-H protons is the signal of the protons of tetramethylsilane ... 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. pantone 161333
