Characterization and Assignment of Far Infrared Absorption Bands of K+ in Muscovite
Dichroism Far Infrared Muscovite Potassium Transition Moment Vibration Mode
2011/12/6
Abstract: To assign far infrared (FIR) absorption bands of K+ in muscovite, dichroic experiments were performed. For a muscovite crystal rotated about a crystallographic axis, c*, a, or b, two bands c...
Far-Infrared Study of the Interlayer Torsional-Vibrational Mode of Mixed-Layer Illite/Smectites
Burial diagenesis Far-infrared Illite/smectite Miocene shale Terrebonne Parish Louisiana X-ray diffraction
2011/12/1
Abstract: Investigation of mixed-layer illite/smectites with far-infrared (FIR) spectroscopy indicates the presence of torsional mode absorption bands associated with interlayer fixed-K sites. By cont...
Assignment of the Far-Infrared Absorption Bands of K in Micas
Dichroism Far-infrared spectroscopy Mica Potassium Vermiculite
2011/12/31
To identify the far-infrared (FIR) absorption bands related to K cations in micas, spectra of muscovite, phlogopite, and biotite were compared with the spectra of pyrophyllite and talc, which have no ...
Far-Infrared Study of Potassium in Micas
Biotite Dehydroxylation Far-infrared spectroscopy Muscovite Phlogopite Potassium
