WebbSeveral general effects on IR frequencies are summarized as follows: 1. Multiple bonds are stronger than single bonds and thus have larger force constants and absorb at higher frequencies than single bonds. For example, 2. More polar bonds are generally stronger than less polar bonds and conse-quently absorb at higher frequencies. 3.
