A Condensed Guide to Spectroscopy: The Spectroscopy Pack PDF

  • This 15-page printable PDF summarizes all the key concepts you’ll need for spectroscopy topics in a typical introductory organic chemistry course.
  • Includes key summaries of NMR, IR, UV-Vis, mass spectrometry and more.
  • Full-color, printable PDF file. No physical item will be mailed to you.

This PDF is included with the MOC Membership. (Alternatively they can be purchased separately from the online store).
