Strategies for Solving Problems using NMR, IR 1. First of all determine the Index of Hydrogen Deficiency (IHD) After assigning partial structures on the 1H-NMR spectrum try to place them together to form the compound. Next, try to generate a spectrum from the proposed structure and compare it to the Problem 1: Provide a structure of a compound having a molecular formula of C 5H 10O 2 that is consistent with the following spectra. SHOW your work and assign all relevant peaks in the IR and 1H NMR spectra. To confirm your choice, predict the splitting patterns

A Guide to Solving NMR Problems NMR spectroscopy is a great tool for determining structures of organic compounds.
