The bending-mode absorptions described on the preceding page are to be labelled, and the specific entry in Table 15-3 to which they correspond is to be identified. Concept introduction: Alkenes and aromatic rings both contain C=C double bonds in their Lewis structures, but their C=C stretching modes of vibration appear differently in an IR spectrum. An alkene C=C stretch generally appears as a single peak in the range 1620–1680 cm -1 . Aromatic C=C stretches generally appear as two or three peaks in the range 1450–1600 cm -1 .

UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinc…

Chapter 15, Problem 15.20YT

Interpretation Introduction

Interpretation:

The bending-mode absorptions described on the preceding page are to be labelled, and the specific entry in Table 15-3 to which they correspond is to be identified.

Concept introduction:

Alkenes and aromatic rings both contain C=C double bonds in their Lewis structures, but their C=C stretching modes of vibration appear differently in an IR spectrum. An alkene C=C stretch generally appears as a single peak in the range 1620–1680 cm^-1. Aromatic C=C stretches generally appear as two or three peaks in the range 1450–1600 cm^-1.
