Welcome to the GEEM website. We are located in the Department of Chemistry at the Federal University of Santa Catarina, Florianópolis, Brazil. We are committed to shedding light on the physical nature of unusual bonding situations, particularly those that take part in molecular recognition and self-assembly processes, materials, and transition metal complexes. The website is oriented towards people interested in computational chemistry and its applications, providing them with a glimpse of our ongoing research activities as well as ourselves.
