Micro-Raman spectra of carbonates, silica and amorphous plagioclase, and both micro-Raman and IR reflectance spectra of phosphates in ALH84001 are reported. Data from these vibrational techniques combined with electron microprobe analyses show that (

By using a thin 13C diamond chip together with a 12C diamond chip as sensors, the diamond Raman spectra provide the means to measure pressure precisely (±0.3 GPa) at any temperature (10–1200 K) and simultaneous hydrostatic (or quasihydrostatic) pr

We have measured the Raman spectra of ethylene-vinyl alcohol copolymer (EVOH) and poly(vinyl alcohol) (PVOH). Spectra of 88% hydrolyzed PVOH were examined from the partially crystalline solid, from PVOH dissolved in both H2O and D2O, and from films p

Disordering of the cations between the T and M sites complicates the analysis of the vibrational spectra of the ${\mathrm{MgAl}}_{2}$${\mathrm{O}}_{4}$ spinel, as well as many other spinels; thus, the Raman spectrum of ${\mathrm{MgAl}}_{2}$${\mathrm{
