摘      要：The calculated Raman spectra disclose that alumina polymorphs of nordstrandite, gibbsite, diaspore, boehmite, bayerite and α-Al2O3 display different phonon behaviors, which can be attributed to their internal crystal structure changes. The strongest Raman peaks of nordstrandite, gibbsite, diaspore, boehmite, bayerite and α-Al2O3 are located at 214.2cm-1, 3314.4cm-1, 2298.6cm-1, 747.7cm-1, 3484.6cm-1 and 529.2cm-1, respectively. The characterizations in Raman spectra of those polymorphs are obviously different, which can be used in fingerprints to identify the alumina polymorphs structure.
