Unsynchronized Resonating of Covalent Bond Theory [A Teoria da Ressonancia N o-Sincronizada das Liga es Covalentes]

The fundamental features of the unsynchronized resonating of covalent bond (RVB) theory as originally developed by Linus Pauling are presented. The resonance of covalent bonds is widely known by chemists; however, the idea of unsynchronized resonance is unfamiliar. Nevertheless, the versatility of the RVB theory can be seen in the investigation of many systems and phenomena, such as superconductivity, magnetism, catalysis, besides the description of the metals, alloys and intermetallic compounds. The RVB theory has the advantage of relating the properties of a system with the nature of the atoms that constitute it
