I am having some difficulties to identify compounds using their HNMR spectra. Can someone help me please.

Thank you.

This is tricky if you would like us to refer to spectra as this is a text only site. If you want help interpreting a particular spectrum you will need to convert it to a text description.

Do you want suggestions on texts or web sites to look at?

Yes, I can provide you with some suggestions on texts and websites that can help you in identifying compounds using their HNMR spectra.

1. "Interpretation of Carbon-13 NMR Spectra" by Robert J. Lancashire: This book provides a comprehensive guide to interpreting carbon-13 NMR spectra, which can be useful in combination with HNMR spectra. It covers the principles of NMR spectroscopy, chemical shifts, coupling constants, and analysis of spectra.

2. "Spectrometric Identification of Organic Compounds" by Robert M. Silverstein: This book is widely considered as a standard reference for interpreting various spectroscopic techniques, including HNMR spectra. It provides detailed explanations and examples of spectral interpretations, including strategies on using chemical shifts, coupling constants, and other spectral features.

3. "Organic Structures from Spectra" by Leslie D. Field, Seeram Ramakrishna, and Joe S. Clark: This book focuses on the interpretation of NMR, IR, MS, and UV-Vis spectra to determine the structures of organic compounds. It contains numerous spectra examples and step-by-step discussions on how to analyze and identify compound structures based on their spectral features.

In addition to these books, there are several online resources that can assist you in interpreting HNMR spectra:

- "NMRShiftDB" (www.nmrshiftdb.org): This online database provides access to a large collection of NMR spectra, including HNMR. You can input the chemical shift data of your compound and compare it with the database spectra to help identify the compound.

- "ChemSpider" (www.chemspider.com): This website offers a chemical structure search tool, allowing you to input the HNMR data (chemical shifts, coupling constants) and search for compounds with similar spectra. It can be helpful in narrowing down the possible compounds based on their spectroscopic data.

- "Spectra School" (www.spectraschool.org): This website provides educational resources and tutorials on spectroscopy, including HNMR interpretation. It offers interactive learning modules and practice exercises to help you improve your skills in analyzing HNMR spectra.

By referring to these resources, you will be able to gain a better understanding of how to interpret HNMR spectra and identify compounds based on their spectral features.
