Tetrahedral in a sentence

Also, in part due to self-duality of the tetrahedron, only one Archimedean solid has only tetrahedral symmetry.

Alternately, the numbers on a tetrahedral die can be placed at the middles of the edges, in which case the numbers around the base are read.

Because the fluorine and chlorine atoms differ greatly in size and effective charge from hydrogen and from each other, the methane-derived CFCs deviate from perfect tetrahedral symmetry.

Bell's coffin was constructed of Beinn Bhreagh pine by his laboratory staff, lined with the same red silk fabric used in his tetrahedral kite experiments.

By contrast, the modern structure of (meta) periodic acid has all four oxygen atoms surrounding the iodine in a tetrahedral geometry.

Dyar and Gunter, pp. 110–113 Micas are also T-O-T-stacked phyllosilicates, but differ from the other T-O-T and T-O-stacked subclass members in that they incorporate aluminium into the tetrahedral sheets (clay minerals have Al 3+ in octahedral sites).

Each of the tetrahedral compounds is self-dual, and the compound of 5 cubes is dual to the compound of 5 octahedra.

Experimental chemistry Gas phase The tetrahedral structure of the RfCl 4 molecule Early work on the study of the chemistry of rutherfordium focused on gas thermochromatography and measurement of relative deposition temperature adsorption curves.

For complexes with a tetrahedral surrounding, the d-orbitals again split into two sets, but this time in reverse order.

For instance in a methane molecule ( CHmain ) or an ammonium ion ( NHmain ), four hydrogen atoms surround a central carbon or nitrogen atom with tetrahedral symmetry.

Hemoglobin's quaternary structure comes from its four subunits in roughly a tetrahedral arrangement.

In 1874, Jacobus Henricus van 't Hoff and Joseph Le Bel explained optical activity in terms of the tetrahedral arrangement of the atoms bound to carbon.

In the vast majority of cases, silicon is in four-fold or tetrahedral coordination with oxygen.

In this compound, each of the iridium atoms is bonded to the other three, forming a tetrahedral cluster.

It consists of tetrahedral Pmain molecules, in which each atom is bound to the other three atoms by a single bond.

It used tetrahedral dice.

LiOH, however, has a layered structure, made up of tetrahedral Li(OH) 4 and (OH)Li 4 units.

Many of these are based on a central tetrahedral silicon atom, and some are optically active when central chirality exists.

No long-range order is present, although there is local ordering with respect to the tetrahedral arrangement of oxygen (O) atoms around the silicon (Si) atoms.
