Effect of end groups on the raman spectra of lycopene and β-carotene under high pressure.
The Raman spectra of all-trans-lycopene in n-hexane were measured under high pressure, and the results compared with those of β-carotene. The different pressure effects on Raman spectra are analyzed taking into account the different structures of lycopene and β-carotene molecules. It is concluded that: (a) the vibronic coupling between the S₁ and S₀ states of β-carotene is stronger than that of...
متن کاملEffect of pressure on the Raman anomaly of zinc-blende CuBr and Raman spectra of high-pressure phases
Raman spectra of isotopically pure CuBr (Cu Br) were measured under hydrostatic pressures up to 10 GPa at 10 K. The anomalous line shape of the longitudinal-optic ~LO! scattering in the zinc-blende phase ~CuBr-III, 0–4 GPa!, consisting of a broad structure between 155 and 177 cm, exhibits a continuous change with pressure and develops into a narrow LO phonon peak near 4 GPa. The disappearance o...
متن کاملPulsed remote Raman system for daytime measurements of mineral spectra.
A remote Raman system has been developed utilizing a 532nm pulsed laser and gated intensified charged couple device (ICCD) detector in the oblique geometry. When the system is set for 50m sample distance it is capable of measuring Raman spectra of minerals located at distances in the range of 10-65m from the telescope. Both daytime and nighttime operations are feasible and the spectra of minera...
متن کاملDual Effects of Plant Antioxidants on Neuron Cell Viability
Background : Many studies have focused on oxidative stress induced damage and hence, the protective effects conferred by antioxidants. An example is neurodegenerative diseases which is thought to occur due to neuronal loss associated with oxidative stress. However, some antioxidants such as vitamin E have been shown to also exert pro-oxidative effects at high concentration. Objective : In t...
متن کاملRaman scattering studies on n-heptane under high pressure.
High-pressure Raman scattering studies at ambient temperature are performed on n-heptane. We observe a liquid-solid transition around 1.5 GPa from the changes in the Raman spectra. This has been reported in earlier works. With increasing pressure, we observe large changes in the Raman modes and the spectra show a distinct change around 7.5 GPa. This marks the solid-solid transition at 7.5 GPa o...
