This lists the character tables for the more common molecular point groups used in the study of molecular symmetry. These tables are based on the group-theoretical treatment of the symmetry operations present in common molecules, and are useful in molecular spectroscopy and quantum chemistry. Information regarding the use of the tables, as well ...
Pat Sheehan, born c. 1945, is a retired American television news anchor from Connecticut.. Sheehan spent most of his TV journalism career at WTNH-TV from 1971-74 and from 1979-83, WFSB-TV from 1974-79 and from 1983-88, and WTIC-TV from 1989-99, as a reporter, and then an anchor, that made him a Connecticut Television icon.
WTNH (channel 8) is a television station licensed to New Haven, Connecticut, United States, serving the Hartford–New Haven market as an affiliate of ABC.It is owned by Nexstar Media Group alongside MyNetworkTV affiliate WCTX (channel 59), also licensed to New Haven.
There are five fundamental symmetry classes which have triangular fundamental domains: dihedral, cyclic, tetrahedral, octahedral, and icosahedral symmetry. This article lists the groups by Schoenflies notation , Coxeter notation , [ 1 ] orbifold notation , [ 2 ] and order.
This article summarizes the classes of discrete symmetry groups of the Euclidean plane. The symmetry groups are named here by three naming schemes: International notation, orbifold notation, and Coxeter notation. There are three kinds of symmetry groups of the plane: 2 families of rosette groups – 2D point groups; 7 frieze groups – 2D line ...
D nd (or D nv), [2n,2 +], (2*n) of order 4n – antiprismatic symmetry or full gyro-n-gonal group (abstract group: Dih 2n). For a given n, all three have n-fold rotational symmetry about one axis (rotation by an angle of 360°/n does not change the object), and 2-fold rotational symmetry about a perpendicular axis, hence about n of those.
It is also the symmetry of a pyritohedron, which is extremely similar to the cube described, with each rectangle replaced by a pentagon with one symmetry axis and 4 equal sides and 1 different side (the one corresponding to the line segment dividing the cube's face); i.e., the cube's faces bulge out at the dividing line and become narrower there.
Isabelle worked for News 8 (WTNH) in Connecticut from December 2002 to November 2013 where, as Sonia Baghdady, she anchored the weekday evening shows "News 8 at 5, 5:30 and 11pm". Before joining WTNH, she was an anchor and reporter for WWLP in Springfield, Massachusetts, and a reporter for a Long Island News 12 affiliate.
