NMRaktive
NMRaktive refers to a concept in nuclear magnetic resonance spectroscopy, specifically the process of making signals invisible in an NMR signal. This phenomenon is also known as "invisible NMR signal" or "hidden NMR signal". In the context of NMR spectroscopy, the appearance of an NMR signal is determined by the presence of magnetically equivalent nuclei, which are nuclei that experience the same magnetic interactions.
NMRaktive occurs when the magnetic equivalence of nuclei is determined not by their scalar couplings, but by
The presence of NMRaktive signals can lead to the underestimation of spin statistics in the resulting NMR
Research on NMRaktive has been conducted primarily in the fields of organic and medicinal chemistry, where
