Francisco F. de Sousa scite author profile

MoO 4 undergoes a sequence of three phase transitions, which were observed at 783-803, 823-913 and 943-950 K. In both crystals, a strong first-order phase transition occurs as indicated by the behavior of the Raman modes: the Raman bands split and new bands appear below 100 cm −1 . These transitions are connected with tilting and/or rotations of the WO 4 and MoO 4 tetrahedra, which leads to a disorder at the WO 4 and MoO 4 sites.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
