Abstract The present paper investigates the Raman spectrum of n-pentadecane in diamond anvil cell under a temperature up to 350 ℃. The result shows that the pressure increases at elevated temperature, but the effect of pressure on the stretching vibrational modes of CH₃ and CH₂ is inverse to that of temperature. The action of temperature is weaker than that of pressure. So the spectral profile of stretching vibrational modes of CH₃ and CH₂ gradually changes and the Raman shift moves to higher frequency with increasing temperature and pressure. It is indicated that the bonding energy of C—H bonding increases with temperature and pressure. In addition, the generation of a new substance resulted in a drastic fluorescence appearance, so the detection of the Raman spectrum of n-pentadecane failed. During the authors’ experiment, the author observed a dependence of the drastic fluorescence occurrence time on temperature and pressure conditions.
