Characteristic vibrational frequency
WebThe frequency of the absorbed radiation causes the molecular vibrational frequency for the absorption process: ˉν(cm − 1) = 1 λ(μm) × 104(μm cm) = ν(Hz) c(cm / s) Equation 5.5.5 can be modified so that the radiation can be expressed in wavenumbers ˜νm = 1 2πc√k μ Webpaper we discuss the characteristic vibrational frequencies of compounds containing the Si-0-Si group (e.g. the disiloxanes) , the P-0-P group (e.g. diphosphorpl compounds), and the C1-0-Cl group. From the frequencies and calculated force constants, inform- ation is obtained concerning the nature of Si-0-Si, P-0-P, S-0-S, and C1-0-C1 bonds.
