However, the fluxional process is not fast enough for IR spectrum.

A classic example of a fluxional molecule is dimethylformamide.

The methanium ion is therefore considered a fluxional molecule.

The Cope rearrangement causes the fluxional states of the molecules in the bullvalene family.

While Newton began development of his fluxional calculus in 1665-1666 his findings did not become widely circulated until later.

Molecules with polyhapto ligands are often "fluxional", also known as stereochemically non-rigid.

The technique applies to barriers of 8-14 kcal/mol, and species exhibiting such dynamics are often called "fluxional".

Since Newton's work at issue did employ the fluxional notation, anyone building on that work would have to invent a notation, but some deny this.

The prototypical fluxional molecule is the carbonium ion, which is protonated methane, CH.

Pentacoordinate molecules of trigonal pyramidal geometry typically exhibit a particular kind of low energy fluxional behavior called Berry pseudorotation.

In this way it is possible to activate the fluxional state by adding base and deactivate it again by removing the base:

This results in a diverse range of coordination geometries, many of which are irregular, and also manifests itself in the highly fluxional nature of the complexes.

He discovered fluxional processes in both diamagnetic and paramagnetic π-allyl organometallic complexes bearing M-H-C agostic interactions.

It is a fluxional molecule in which the axial (ax) and equatorial (eq) fluorine atoms interchange positions by the Berry pseudorotation mechanism.

Often, a molecule is considered fluxional if its spectroscopic signature exhibits line-broadening (beyond that dictated by the Heisenberg Uncertainty Principle) due to chemical exchange.

Finally, in 1740, Thomas Simpson described Newton's method as an iterative method for solving general nonlinear equations using fluxional calculus, essentially giving the description above.

Fluxional process for cyclopentadienyliron dicarbonyl dimer is so fast that only averaged single signal is observed in H NMR spectrum.

The complex TiCl(acac) is fluxional in solution, the NMR spectrum exhibiting a single methyl resonance at room temperature.

Since 1992, he has continued to produce a fluxional interactive art spectacle/installation named "COSMOGARDEN" (the cosmic garden).

XeF is a fluxional molecule with a distorted octahedral structure, which is, according to VSEPR theory, caused by the non-bonding lone pair.

Bullvalene is a hydrocarbon with the chemical formula CH with the unusual property that the chemical bonds making up the molecule are constantly rearranging as in fluxional molecules.

As a fluxional molecule, bullvalene is subject to degenerate Cope rearrangements, with the result that all carbon atoms and hydrogen atoms appear equivalent on the NMR timescale.

Fe(CO) is the archetypal fluxional molecule due to the rapid interchange of the axial and equatorial CO groups via the Berry mechanism on the NMR timescale.

For all symbols are fluxional; all language is vehicular and transitive, and is good, as ferries and horses are, for conveyance, not as farms and houses are, for homestead.

There is something equivocal in all the words in use to express the excellence of manners and social cultivation, because the quantities are fluxional, and the last effect is assumed by the senses as the cause.

Even before the strange business in Tokyo last weekend, when somebody named Buster Douglas knocked out Mike Tyson, Dr. Reitman was aware of the fluxionary nature of boxing.
