Introduction

NMR spectroscopy is based on the fundamental property of certain atomic nuclei, known as nuclear spin. When placed in a magnetic field and exposed to radiofrequency pulses, these nuclei absorb and reemit energy at characteristic frequencies, providing unique signals that can be harnessed for structural analysis [1].

Methodology

Multinuclear NMR spectroscopy expands upon this principle by incorporating a variety of nuclei, each with its own distinctive properties. Common nuclei studied in MMR spectroscopy include hydrogen (¹H), carbon-13 (¹³C), nitrogen-15 (¹⁵N), phosphorus-31 (³¹P), and many others. The ability to examine multiple nuclei grants researchers a broader view of molecular structures and interactions [2,3].

Applications of MMR spectroscopy

Structure elucidation: MMR spectroscopy plays a pivotal role in determining the three-dimensional structures of complex molecules. By examining different nuclei within a molecule, researchers can piece together a detailed picture of its architecture, aiding drug discovery, and materials science.

Protein and biomolecular studies: In the realm of biochemistry, MMR spectroscopy is indispensable for studying proteins, nucleic acids, and other biomolecules. It allows researchers to investigate the folding, dynamics, and interactions of these crucial components of living organisms [4,5].

Metabolomics: MMR spectroscopy finds application in metabolomics, the study of small molecule metabolites in biological systems. By analysing nuclei like ¹H and ¹³C, scientists can gain insights into metabolic pathways and understand physiological changes in cells and tissues.

Material science: Researchers in material science leverage MMR spectroscopy to analyze the composition and properties of materials, including polymers and catalysts. The technique aids in optimizing material design for specific applications [6].

Phosphorus NMR: Phosphorus-31 NMR is particularly valuable in studying phosphorus-containing compounds, such as nucleic acids and phospholipids. This provides essential information about cellular processes and membrane structure.

Challenges and future developments

While MMR spectroscopy offers remarkable insights, it is not without challenges. Obtaining high-quality spectra can be demanding, and interpreting complex data requires expertise. Technological advancements, however, continue to address these challenges, with improvements in instrumentation, sensitivity, and data analysis methods [7 ,8].

The future of MMR spectroscopy holds promise for even greater capabilities. Ongoing research focuses on enhancing resolution, expanding the range of nuclei that can be studied, and developing novel applications in emerging fields like nanotechnology and medicine.
