Hydroxyl-Stretching Bands in Curve-Fitted Micro-Raman, Photoacoustic and Transmission Infrared Spectra of Dickite from St. Claire, Pennsylvania
Curve-fitting Dickite Infrared LO and TO Crystal Modes Micro-Raman OH bands SEM
2011/12/5
Abstract: The OH-stretching region in curve-fitted micro-Raman, photoacoustic and transmission IR spectra of St. Claire dickite was investigated. Polarized Raman spectra recorded from the (001) and (0...

2011/12/9
Abstract: A large and representative collection of clay-size dioctahedral mica minerals differing in their chemical compositions has been studied by infrared (IR) spectroscopy in the OH stretching vib...
Infrared Spectra of Thiolane and Tetramethylene Sulfoxide Adsorbed on Montmorillonite
Adsorption Infrared spectroscopy Montmorillonite Tetramethylene sulfoxide Thiolane
2011/11/25
Abstract: Infrared spectra (4000–1200 cm−1) were obtained for several homoionic montmorillonite films on which tetramethylene sulfoxide (TMSO) or thiolane were adsorbed at various temperatures a...
Qualitative and Quantitative Study of Stacking Faults in a Hydrazine Treated Kaolinite桼elationship with the Infrared Spectra
Qualitative Hydrazine Treated Kaolinite Infrared Spectra
2012/2/13
Artificial stacking faults can be created within a well-crystallized kaolinite by intercalating and removing hydrazine. X-ray powder patterns with electron microscopy show that the created defects are...
Interpretation of Infrared Spectra of Oxidized and Reduced Nontronite
Oxidized Reduced Nontronite Interpretation structural hydroxyls
2012/2/13
Infrared spectra of nontronite reveal shifts to lower wave, number in peaks located at 3570, 1030, and 821 cm−1, which are assigned to vibrational modes for O-H stretching, Si-Ob (basal oxygens)...
