Abstract
Publisher Summary This chapter provides an overview of the vibrations of olefin groups. Olefinic CH stretching vibrations, olefinic C=C stretching vibrations, olefinic CH and CH2 in-plane bending vibrations, and olefinic hydrogen wagging vibrations are discussed in the chapter. Olefinic CH stretching frequencies occur at 3130–2980 cm−1. The C=C stretch vibrations interact to some extent with =CH2 deformation vibration and the attached single bond stretching vibration, because nonhydrogen substituent atoms remain nearly motionless for this mode. The C=C stretching frequency is affected by the changes in these interactions and by mesomeric and inductive effects that alter the strength of the C=C and attached C—X bonds. The chapter presents the general infrared radiation (IR) spectra expected for ethylenes with alkane substituents.
