Combination scattering and infrared absorption spectra of cyclohexane molecule

Abstract

This study employs Raman and infrared spectroscopy to investigate the characteristics of C-H interatomic bonds in cyclohexane, a member of the aromatic hydrocarbon family. The analysis spans a frequency range of 0–3500 cm⁻¹. Our findings reveal the unique role of C-H bonds in shaping both Raman scattering and infrared absorption spectra. We provide several theoretical parameters that elucidate the vibrational motion of the molecule linked to the C-H bond. Additionally, a structural model of the cyclohexane molecule was developed through quantum chemical calculations, offering insights into its molecular dynamics. This work enhances our understanding of cyclohexane’s spectral properties and the behavior of C-H bonds within aromatic compounds.
