Dear Rietvelders, I am searching for the structure of various transition aluminas (especially rho, eta, khi, gamma, delta and sigma) to perform ab-initio calculations of their infrared spectra. Could you, please, inform me about those structures ? Best regards, Dr L. Favaro Laboratoire LEMHE Université Paris-Sud Orsay, France
