Study on the Structure and Generation Mechanism of Intermediate (6AlO–OH) in Decomposition Process oof intermediate was explored. The molecular structure and spectroscopic property (Raman and UV-Vis spectra) of intermediate (6AlO–OH) were calculated by the quantum computational chemistry method based on DFT method employing B3LYP level with 6-311+G (d, p) basis set. By analyzing the experimental a
