Vibrations yeild new type of bond?

Vibrational bond ?


New type of chemical bond:

New type of chemical bond is listed here below.Chemists confirm the existence of a new type of chemical bonds!

Chemistry has many laws, one of which is that the rate of reaction increases when the temperature increases.

Interaction between bromine and muonium:

So, in 1989, chemists were experimenting with a nuclear accelerator in Vancouver that noticed that the interaction between bromine and muonium – a radioactive isotope of hydrogen – slowed down as the temperature increased, making them feel baffled.

Donald Fleming:

Donald Fleming, a chemist at the University of British Columbia who did the experiment, thought that perhaps when bromine and muonium mixed together they formed an intermediate structure holding each other in a “vibrational bonding,” a bond that chemists had assumed as a theoretical possibility before that decade.

In this scenario :

In this scenario the light muonium atom moves rapidly. Between two bromine atoms, a weight, like two table tennis balls, floundering between two bowling balls, Fleming says. 

The atom will bind the two bromine atoms together for a short time and reduce the total energy and thus the speed of the reaction.

At the time of the experiment, the tools needed to examine millisecond reactions closely enough to determine if vibrational bonds were found or not were not available. 

Experiment in the Rutherford Appleton Laboratory in England:

Over the past 25 years, chemists’ ability to track simple changes in energy levels within reactions has greatly improved, so Fleming and his colleagues re-experimented again three years ago in the Rutherford Appleton Laboratory in England, based on calculations from both experiments and the work of some theoretical chemists.

At the Free University of Berlin and Saitama University in Japan:

They concluded that bromine and aluminum definitely formed a new kind of temporary bond. Its vibrational nature reduced the full energy of the mesBM synthesis, thus explaining why the reaction slowed despite the increase in temperature.

Confirmation of vibrational bonds:

The work confirmed that the vibrational bonds, although they are transient, should be added to the list of chemical bonds. And although the bromine-muonium reaction is an ideal system for stabilizing vibrational bonds, Fleming expects the phenomenon to occur in other interactions between light and heavy atoms.
