Resonance


Reasonable Resonance
The resonance frequency of each vibration can be found using the formula fn = (v/ λn) = (nv/2L). 



Resonant Frequencies

 The "true" molecular electronic structure is a superposition of all reasonable resonance 
structures. The equivalent structures contribute equally and different structures contribute 
according to their relative importance. 



 Resonance Structure

Any of two or more possible structures of the same compound that have identical geometry but different arrangements of their paired electrons; none of the structures has physical reality or adequately accounts for the properties of the compound, which exists as an intermediate form.
