Abstract

In this comment to a recent paper [Anal. Chim. Acta 585 (2007) 241-245], we report a comparison study on Mn oxide-related compounds with different crystallographic forms, which distinguish between beta-MnO(2) and alpha-MnO(2) type materials via Raman scattering (RS) spectroscopy. The tetragonal rutile-type beta-MnO(2) is characterized by a RS band at approximately 667cm(-1) of symmetry A(1g), whereas the alpha-MnO(2) type materials feature two main RS contributions at about 574 and 634cm(-1), belonging to A(g) spectroscopic species of a tetragonal hollandite-type framework. These data represent a clear signature for identifying beta-MnO(2) and alpha-MnO(2) type materials via RS spectroscopy.
