What: "These electrons are the glue that holds together a chemical bond between the atoms.A chemical bond is like a spring in that the two nuclei on either end of the bond have some freedom to move closer or farther apart. There is an optimum, lowest-energy distance for the nuclei to be from each other. If they are any closer, the positive nuclei will start to repeal each other. Farther from each other, you get less energy gain from sharing the electrons. A bond vibrates when the distance between the nuclei oscillates between the nuclei being too close together, then too far apart. This is called a stretching vibration."
