The NMR Facility at LAQV (FCT NOVA, University of Aveiro, and UPORTO) is integrated in the Portuguese Nuclear Magnetic Resonance Network (PTNMR). PTNMR is a distributed National Research Infrastructure that integrates the Portuguese Roadmap of Research Infrastructures. PTNMR provides coordinated access to a national platform of equipment, resources, services, and skills in NMR for participating institutions and the scientific community, from both national and international R&D industry and academia. The main goal is the maintenance of a single platform that supports the technical integration, sharing of resources and a combined management of the national NMR infrastructure, enabling access to modern and fully operational NMR spectrometers and support of R&D initiatives. The NMR facility of FCT NOVA, hosted in the Chemistry Department, pioneered in Portugal in the use of NMR for the determination of protein structures. Currently, we still support many research projects focused on the determination of protein structure and dynamics but most of the research being conducted is related to the study of molecular interactions and molecular recognition in a wide range of chemical and biochemical systems. The facility is also strongly committed to providing NMR routine services to support in-house synthesis and chemical (bio) engineering research groups. The Magnetic Resonance facility of LAQV-UPORTO is part of the Structural Analysis Laboratory of the University of Porto Materials Center (CEMUP). The three spectrometers available provide routine services to support in-house researchers, graduate, and post-graduate students as well as external users. The NMR facility at the University of Aveiro hosted at the chemistry department is constituted by 5 NMR spectrometers and allows us to cover a wide range of applications, from the comprehensive characterization of the chemical structure, conformations, and configurations of synthetic and natural molecules to metabolomics analysis for biochemical characterization. However, there are also spectrometers devoted to solid-state NMR using high-resolution methods to study small molecules, inorganic materials, and inorganic-organic hybrid materials.
