Oxygen coefficient

LFL is the volume percent of fuel in air at the lower flammability limit, and z is the stoichiometric oxygen coefficient from the combustion reaction given by Equation 6-9.

Although the arguments given above are based only on orbital energies, donor substituents on the nitrone carbon have an additional influence on the nitrone HOMO, causing the oxygen coefficient to increase at the expense of the carbon23. This also reinforces the preference for 4-substituted adduct as the nitrone IP decreases.

Oxygen coefficient of explosive is the saturated degree of explosive molecule with oxygen. For example, oxygen coefficient of C Hi,0,Nrf explosive can be calculated according to the following equation ... 

Thus, oxygen coefficient is the percentage of oxygen contained in the explosive over the required oxygen to completely oxidize carbon and hydrogen in the explosive. Same as the oxygen balance, it is also used to measure the relative relationship between oxygen content of the explosive and its flammable element content. Similarly, it is related to detonation products of the explosive. 

The following two examples are going to show the calculation of oxygen coefficient...

Under the influence of the adsorbate, the surface structure may switch periodically between more (=non-reconstructed) and less reactive (=reconstructed) state, whereby the driving forces are the difference in surface free energy of the clean planes on the one hand and the difference in CO adsorption energy on the other. In other words, the reconstructed phase adsorbs CO more rapidly than it is reacted. Thus, the CO coverage increases beyond its critical value for nucleation of the structural transformation into the non-reconstructed state. The latter exhibits an increased oxygen coefficient so that CO is removed more rapidly from the surface. As a result, the CO coverage drops and the surface transforms back to reconstructed states.
