In general, the stretching absorptions of CLH bonds involving sp2-hy-bridized carbons occur at wavenumbers greater than 3000 cm_1, and the stretching absorp-tions of CLH bonds involving sp3-hybridized carbons occur at wavenumbers less than 3000 cm_1. Thus, 1-octene has a ACLH stretching absorption at 3080 cm_1 (Fig. 12.10a), and

WebThe frequency for a C-H bond is approximately 3000 cm-1. Compare this value with that calculated for a bond between carbon and chlorine; here, (M 1 +M 2)/M 1 M 2 = 0.11; the frequency for a C-Cl bond is approximately 600-800 cm-1. v (wavenumber) depends on the strength of the bond between the atoms M 1 and M 2 as given by K, the force constant ... Web[1] [2] In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify chemical compounds based on the way infrared radiation is absorbed by the compound. The absorptions in this range do not apply only to bonds in organic molecules.
