Through the usage of EPR spectroscopy, the absolute rate constants for unimolecular reactions can be measured with a variety of temperatures.
12.
The unimolecular decompositions that acetyl cyanide undergo have been confirmed to be less energetically favorable than the molecule undergoing isomerization to acetyl isocyanide.
13.
It breaks down an apparently " unimolecular " reaction into two elementary steps, with a rate constant for each elementary step.
14.
To account accurately for the pressure-dependence of rate constants for unimolecular reactions, more elaborate theories are required such as the RRKM theory.
15.
For a unimolecular reaction or step the rate is proportional to the concentration of molecules of reactant, so that the rate law is first order.
16.
However, acetyl cyanide, also a member of this family, breaks down through this unimolecular decomposition at 470 �C . This reaction occurs through decarbonylation.
17.
As with unimolecular reactions, the keys to the qualitative and quantitative understanding of the many processes in emulsion polymerisation are the rate coefficients of the individual steps.
18.
A "'unimolecular rectifier "'is a single organic molecule which functions as a rectifier ( one-way conductor ) of electric current.
19.
In the field of chemical kinetics, he proposed the Lindemann mechanism in 1921 for unimolecular chemical reactions, and showed that the first step is one of bimolecular activation.
20.
His main research interests were quantum mechanics, electromotive force, atomic structure, electron emission, unimolecular force, and high vacuum, and he authored several standard science textbooks.
