Stretching frequency formula

WebStretching frequency: The energy of photons absorbed to cause molecular vibrations, plotted as the x -axis of an infrared spectrum. The term can be misleading because the infrared spectrum x -axis energy unit is cm -1 , a wavelength unit, and not a frequency unit. WebAn IR spectrum can be visualized in a graph of infrared light absorbance (or transmittance) on the vertical axis vs. frequency, wavenumber or wavelength on the horizontal axis. Typical units of wavenumber used in IR …

http://www.chem.ucla.edu/~harding/IGOC/S/stretching_frequency.html WebThe vibrational frequency of a vibrating two-body system depends on both the force constant and the reduced mass of the system: ν ∝ √ (k/µ). The force constant depends on the strength of the bond. A C=C bond is about 1.5 times as strong as a C=C bond. That would make it vibrate faster than a C-H bond. But µ (C-C) = 6, while µ (C-H) = 0.92. phil costley dmu https://astcc.net
