|dc.description.abstract||The Structure. The ethylene oxide molecule consists of seven atoms: one oxygen atom, two carbon atoms, and four hydrogen atoms. The two carbon atoms and the oxygen atom. Form an isosceles triangle. Two hydrogen a toms are attached to each carbon atom in such a way that each CH2 plane is perpendicular to the C20 plane. The Symmetry. The molecule has a two-fold axis of symmetry passing through the oxygen atom and bisecting the COC angle. The molecule also has two planes of symme try, one coinciding with the C2O plane, the other perpendicular to it and intersecting it in the two-fold axis. Because of this symmetry, the ethylene oxide molecule belong to the C2O point group. The Species. There are fifteen (3N-6) normal vibration frequencies, all of which are non.-degenerate. Five of these vibrations (A,) are symmetrica l to the symmetry axis and the plane; four vibrations (B,) are symmetrical to the C2O plane and anti-symmetrical to the axis; three (A2) are symmetrical to the axis and anti-symmetrical to the plane; and three (B2) are anti-symr.netrical to both the plane and the axis. All of the vibrations are active in the Raman spectra and all except the three A1 vibrations are active in the infrared. [TRUNCATED]||en_US|
