“…At the other end of this region, around 1710 cm −1 , a C=O bond seems reasonably prominent. The C=O bonds in non-oxidized oil samples could possibly be attributed to residual dewaxing ketones, antiwear β-lactam, or possibly esters shifted to lower frequencies with conjugation [33][34][35]. As one might expect, the spectra of these oil samples are so active across the entire range that feasible confirmation peaks for these organics appear in the data.…”

Fourier Transform-Infrared (FT-IR) spectroscopy was used to analyze gasoline engine oil (SAE 5W20) samples that were exposed to seven different oxidation times (0 h, 24 h, 48 h, 72 h, 96 h, 120 h, and 144 h) to determine the best wavenumbers and wavenumber ranges for the discrimination of the oxidation times. The thermal oxidation process generated oil samples with varying total base number (TBN) levels. Each wavenumber (400–3900 cm−1) and wavenumber ranges identified from the literature and this study were statistically analyzed to determine which wavenumbers and wavenumber ranges could discriminate among all oxidation times. Linear regression was used with the best wavenumbers and wavenumber ranges to predict oxidation time.
