fluxional molecule s.
Kaynak: BullvaleneThe Cope rearrangement causes the 
fluxional  states of the molecules in the bullvalene  family. Mechanism : Although the Cope rearrangement is

fluxional forms and series to be found in no work of foreign countries Whish was also a linguist  and had prepared a
Kaynak: C. M. WhishSince 1992, he has continued to produce a 
fluxional interactive art  spectacle /installation  named "COSMOGARDEN " (the cosmic garden).-
Kaynak: Aki KurodaI of the Principia of 1687 did not explain his eventual 
fluxional notation for the calculus in print until 1693 (in part) and 1704 (in full).
Kaynak: Leibniz–Newton calculus controversyHapticity and 
fluxionality: Molecules with polyhapto ligands are often "
fluxional", also known as stereochemically non-rigid.

Kaynak: SadratnamalaHe discovered 
fluxional  processes in both diamagnetic  and paramagnetic  π-allyl organometallic complexes bearing M-H-C agostic
Kaynak: Steven IttelFe(CO)5 is the archetypal 
fluxional molecule  due to the rapid interchange of the axial and equatorial CO groups via the Berry mechanism
