How to fill out H-NMR Interpretation

1. Obtain the H-NMR spectrum of the sample.
2. Identify the chemical shifts (δ) on the spectrum to determine the environment of the hydrogen atoms.
3. Count the number of signals to understand the number of different hydrogen environments present in the molecule.
4. Analyze the multiplicity of each signal (singlet, doublet, triplet, etc.) to gain insight into the number of neighboring hydrogen atoms.
5. Measure the integration of each signal to find out the relative number of hydrogen atoms contributing to each signal.
6. Compare the chemical shifts and integration values with known values to deduce the structure of the molecule.
7. Consider the splitting patterns and coupling constants for more detailed structural information.

What does H NMR show?

Proton nuclear magnetic resonance (proton NMR, hydrogen-1 NMR, or 1H NMR) is the application of nuclear magnetic resonance in NMR spectroscopy with respect to hydrogen-1 nuclei within the molecules of a substance, in order to determine the structure of its molecules.

How to interpret H NMR peaks?

Look for NMR peaks in the 6.0 - 9.0 range. If you are given a number like 5 or 4 alongside that peak, this just tells you how many hydrogen atoms are attached to the ring. If there are 5 hydrogens attached to the ring, then there is only one group substituted into the ring.

What does hydrogen NMR tell you?

Proton nuclear magnetic resonance spectroscopy (proton NMR) can give information about the different environments of hydrogen atoms in an organic molecule, and about how many hydrogen atoms there are in each of these environments.

What do the number of H NMR signals tell you?

The number of NMR signals represents the number of different types of protons in a molecule. This is the example we used in the introduction to NMR spectroscopy: The spectrum has five signals which indicates five types of different protons. So, what does a type of proton mean?

How to read high resolution NMR?

The steps to interpreting a high resolution 1H NMR spectrum and deducing the structure of a molecule are as follows: Count the number of peaks. Use the integration ratio. Look at the singlets first. Consider possible structures of other peaks. Determine the number of H atoms. Draw the structure from each peak.

Why is hydrogen used in NMR?

Proton nuclear magnetic resonance spectroscopy (proton NMR) can give information about the different environments of hydrogen atoms in an organic molecule, and about how many hydrogen atoms there are in each of these environments.
