Nuclear magnetic resonance chemical shift re-referencing

Nuclear Magnetic Resonance (NMR) chemical shift re-referencing refers to the process of adjusting the chemical shifts of NMR signals to a different reference standard or scale. Chemical shifts in NMR spectroscopy are measured in parts per million (ppm) and are typically referenced to a standard compound, such as tetramethylsilane (TMS) for proton (\(^1H\)) and carbon (\(^13C\)) NMR.
