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.
