摘要: Abstract At room temperature the amorphous sulfur, obtained by quenching high melt, slowly crystallizes. After small molecules have been dissolved in CS2 insoluble rest is called Sω. By behaviour of its diffraction pattern it shown here that Sω made up two different long-chain modifications: Sω1 with all molecular screws parallel, very much as Sψ, and Sω2 a layered structure, screw axes successive layers being at right angles to each other (as plywood). The unit cells both allotropes contain left-as well right-handed helical molecules. Points contact work Erametsa Geller are pointed out.
