AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Raman scattering turns out to be very detrimental for long-range Brillouin time-domain analysis. The conditions under which this problem occurs are studied, as well as possible strategies to avoid it. ...
We have investigated the thermal stability of GaN using Raman scattering. Noninvasive optical monitoring of structural damage to GaN by high-temperature anneals in nitrogen ambient has been demonstrated. Characteristic features in the Raman spectrum identi ...
The effect of pressure (up to 22 GPa) and temperature (to 1300 K) on the Raman spectra has been measured for pyrope, grossular and andradite garnets. No phase changes were observed and all Raman modes increase or decrease linearly with pressure and tempera ...
The resonance Raman overtone progressions of I2 in liq. Xe and in CCl4 following excitation in the bound and continuum parts of the B state are discussed and compared with theor. simulations. The intensity distribution of the Raman overtones yields informa ...
