Tree diagram

Definition

A tree diagram in the context of organic chemistry, particularly within nuclear magnetic resonance (NMR) spectroscopy, is a graphical representation used to predict and interpret the complex spin-spin splitting patterns observed in NMR spectra. It visually outlines the possible transitions between energy states of nuclei being studied, helping to elucidate the structure of organic compounds.

Nuclear Magnetic Resonance Spectroscopy:

A technique that exploits the magnetic properties of certain atomic nuclei to determine the physical and chemical properties of atoms or the molecules in which they are contained.

Spin:

Spin Splitting - A phenomenon observed in NMR spectroscopy where the signal of a nucleus is split into multiple peaks due to interactions with neighboring non-equivalent nuclei.

Chemical Shift:

The resonant frequency of a nucleus relative to a standard in an NMR spectrum; it provides information about the electronic environment surrounding the nucleus
