Experiment 3
Determining the Structures of Unknown Molecules Using NMR, IR and Mass Spectroscopy
Background
The theory of infrared spectroscopy, mass spectroscopy and NMR spectroscopy will be covered
in the first two lab periods. Please read chapters 12 and 13 in McMurry for a complete discussion
of these techniques.
Procedure
Part I
The lab consists of four parts. The first part is a thought experiment to be completed as the prelab work.
Consider the following four compounds:
O
H
OH
OH
O
A
B
C
D
Using the knowledge of spectroscopy you gained in the prior two classes, predict what the IR, NMR and
mass spectrum of each would look like and fill in the following table. (Compound 1 was completed for
you as an example):

Part II
The experiment will be carried out in a group of 4, with each student assigned with one
unknown. Carry out the IR of the four unknown compounds together and report your data and
conclusions here.

Part III
If NMR instrument is not ready for usage, use the following NMR spectra to determine
the structure of your unknown.

Part IV
1. Assign the following 1CNMR belongs to your assigned unknown? Explain. Write your
answer on the right side of the correct spectrum.
2. Which of the following MS belongs to your assigned unknown? Explain. Write your
answer on the right side of the correct spectrum.
