An investigation of the lattice and interlayer water vibrational spectral regions of muscovite and vermiculite using Raman microscopy. A Raman microscopic study of layer silicates

Abstract The micro Raman spectrum of ∼100fg of the clay materials Muscovite and Vermiculite in the region of 600 cm −1 −3300 cm −1 is reported. An attempt has been made to assign the observed Raman shifts in particular those of H‐bonded OH − , which may have significance to an understanding of the role which clay plays in the absorption of soil water.
