**This 2nd part of the series shows you how to approach combined spectral problems. Specifically, you will be guided through the solution of two problems in which you are given a molecular formula, a mass spec., and an IR spectrum for each. (Runtime = 13:24)**

**Student Learning Outcomes**

After viewing this tutorial and practicing problems from this website and your textbook, you should be able to:

• Use mass spectrometry and IR spectroscopy to determine possible stuctures for an unknown compound.

**Practice Problems**

Here are some problems to get you started. You should first try each on a piece of paper. Then, place your cursor over the graphic and click on right arrow that appears to see the answer. The right and left arrows allow you to move back and forth between problems. Please note that these are *not* the only types of problems/questions that exist on this topic. Refer to your textbook and any problems your instructor provides you for more practice with this subject.
