WebThe distance between any two adjacent lines in an NMR multiplet peak is called the coupling constant (symbol: J ). This value is measured in Hz. J coupling is mutual, i.e. J AB = J BA always. The distance between the … WebJul 7, 2024 · What is called coupling constant? The distance between any two adjacent lines in the NMR peaks of two sets of equivalent hydrogen nuclei coupled only to each other is the same, which, when expressed in hertz, is called the coupling constant (symbol: J) of the two sets of equivalent hydrogen nuclei. What does J coupling mean? Definition.
