In this paper, the polycrystal defect spinel In21.333S32 (JCPDF No: 84-1385; Sys: Cubic; Lattice: Face-centered) was prepared utilizing the melt-slowly cooling method and its unpolarized and polarized Raman spectra together with the infrared transmission one were studied in detail. Based on microstructural features of defect spinel In21.333S32 (the random distribution of vacancies and indium atoms on tetrahedral sites as well as the strong distortion of octahedral sites) and the polarized spectroscopic characterization, the two strongest peaks at 305 cm-1 and 245 cm-1 were ascribed to the so-called clustering modes, i.e., the A1g symmetric stretching vibrating mode (ν1) of tetrahedral InS4 and octahedral InS6 respectively. In addition, the ascriptions of the distinct peaks or valleys on Raman and infrared spectra of defect spinel In21.333S32 were further proposed in this paper.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
