Jo Ellen Roseman,Luli Sternthe necessity for growing crystals at temperatures above 2000°C increases, the number of crystal growth systems available is extremely limited. Temperature, however, is not the only requirement necessary for successful single crystal growth. Accurate temperature control, controllable vertical and ho

John B. WolfordIn most of the cyclic (.). systems which may be formed by use of either outer or inner . orbitals, cyclic delocalization through the .-orbital center is possible and leads to an increase in stability, but in no case will the (.). system alone lead to an extraordinary ground-state stabilization which can be classified as aromatic.
