A topological defect in structures formed of this element involves a 90 degree rotation of a singlebond.
A topological defect in structures formed of this element involves a 90 degree rotation of a singlebond. A camel hump spectrum occurs at 220 nanometers in UV spectroscopy of another structureformed of this element. That spectrum was discovered by Kratschmer and Huffman, who were thefirst to create macroscopic amounts of that structure by drying a burgundy solution obtained fromdispersing the results of a certain process in benzene. That previously mentioned topological defect isthe (*) Stone-Wales defect, and Harry Kroto and Richard Smalley were awarded the Nobel for discoveringone form of this element. Another form of this element has armchair and zigzag varieties and was"discovered" by Iijima by using the arc vaporization method. For 10 points, name this element that comesin single-walled and multi-walled nanotube forms as well as being the constituent of buckminsterfullerenes.
