M. C. Goldberg K.W. Cunningham 1983 Previous workers have attributed substantial changes in the Raman intensities of the OH stretching bands in solid, powdered gibbsite of surface area 10 m2/g to surface interactions with the adsorbates 093Ca2+,HxPO43x- and SiO2.xH2O. These changes apparently resulted from an unsatisfactory Raman measurement procedure as a re-examination using an internal intensity standard (Na2C2O4 crystals) with gibbsite of surface area 39 m2/g showed no significant changes in the low-frequency band-height ratios of gibbsite and adsorbates.-D.J.M. application/pdf 10.1097/00010694-198308000-00006 en Wolters Kluwer A reexamination of the effects of adsorbates on the Raman spectrum of gibbsite article
