The physicochemical properties (viscosity viscosity index, density, sulfur content, pour point) of base oils (100 NS, 250 NS, VHVI-4, VHVI-6, PAO-4) were determined. The structural group composition of oils was studied by IR spectroscopy on an «Infr

Analytic and computer models of a harmonic oscillator with slowly varying natural frequency of oscillations are considered. The representation of Green's function in the form of harmonic oscillation with an envelope and a phase depending on the natur

A linear multivariate regression model for the IR spectra of gasolineare used in the paper. On the basis of a number of test samples (alkylate, reformate, regular, premium), an equation was obtained for calculating the content of aromatic hydrocarbon
