Outline
This paper mainly studies Raman spectroscopy of C—H stretching vibrational mode of methanol at 2 835 cm-1 from 169.2 up to 713.8 MPa under the temperature of 301 K using cubic zirconium oxide Anvil Cell. The result shows that methanol is stable at the experimental pressure, and the Raman shift of methanol at 2 835 cm-1 shows a linear dependence with pressure. The correlation between pressure and frequency shift of the 2 835 cm-1 Raman line of methanol is described by p=-3.508 9·[(Δνp)2 835]2 + 135.17 (Δνp)2 835+54.397, where 0.1<p (MPa) ≤ 713.8. So methanol can be used as a reliable pressure gauge in high hydrostatic experiments.
