Abstract
Characteristic spectra in the 0.5–2.5 terahertz (THz) range of three commercial derv fuel oils have been obtained using THz time-domain spectroscopy and calculated using density functional theory. The simulated results and experimental absorption curves suggest that the skeleton vibration is predominant in the THz region, and the absorption bumps of diesels are a superposition of various components. The investigation demonstrates that different diesels can be distinguished using THz time-domain spectroscopy and THz technology is a promising method to detect the composition and properties of diesels via chemical analysis.
