WebIn the physical sciences, the wavenumber (also wave number) is the spatial frequency of a wave, either in cycles per unit distance or radians per unit distance. It can be envisaged … 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. WebFeb 2, 2024 · It is defined as the number of radians per unit distance. The SI unit of angular wavenumber is r a d i a n / m e t e r \rm{radian/meter} radian/meter or simply m − 1 \rm m^{-1} m − 1.
