WebA 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. The reduced mass of a C-C pair is about 6.5 times that of a C-H pair. The greater reduced mass makes the C=C bond vibrate much more slowly than a C-H bond.
