Insoluble in= WATER The spectra of 38 FACE (fuels for advanced combustion engines) gasoline blends were calculated using PIONA (paraffin, isoparaffin, olefin, naphthene, and aromatic) class averages of the pure components. Note the strong bands in the 3000-2850 cm-1 region due to C-H stretch. These metrics are regularly updated to reflect usage leading up to the last few days. n-Octane is a hydrocarbon and an alkane that is volatile and very flammable. For permission to reproduce, republish and Since most organic compounds have these features, these C-H vibrations are usually not noted when interpreting a routine IR spectrum. The region from about 1300-900 cm-1 is called the fingerprint region.

A model for the prediction of research octane number (RON) and motor octane number (MON) of hydrocarbon mixtures and gasoline–ethanol blends has been developed based on infrared spectroscopy data of pure components.

The spectra of simple alkanes are characterized by absorptions due to C–H stretching and bending (the C–C stretching and bending bands are either too weak or of too low a frequency to be detected in IR spectroscopy). CT&F - Ciencia, Tecnología y Futuro, 3 (1), 27-28. The bands in this region originate in interacting vibrational modes resulting in a complex absorption pattern. The study sheds light on the significance of dimensional reduction of spectra and shows how it can be used to extract scores with linear correlations to the following important features: molecular weight, paraffinic CH3 groups, paraffinic CH2 groups, paraffinic CH groups, olefinic −CH═CH2 groups, naphthenic CH–CH2 groups, aromatic C–CH groups, ethanolic OH groups, and branching index. The key measurement per- formed on gasoline is the calculation of octane number. In simple alkanes, which have very few bands, each band in the spectrum can be assigned. from the ACS website, either in whole or in part, in either machine-readable form or any other form Usually, this region is quite complex and often difficult to interpret; however, each organic compound has its own unique absorption pattern (or fingerprint) in this region and thus an IR spectrum be used to identify a compound by matching it with a sample of a known compound.

The IR spectrum of octane is shown below. Note that the change in dipole moment with respect to distance for the C-H stretching is greater than that for others shown, which is why the C-H stretch band is the more intense.
