Determining the molecular structure of organic molecules experimentally can be a tricky challenge! Chemists do this by taking a number of different types measurements, and solving the puzzle a bit like solving a jigsaw puzzle. We use techniques such as:

• microanalysis
• mass spectrometry
• infrared spectroscopy
• nuclear magnetic resonance spectroscopy

This app allows you to be a 'chemical detective' and take all of the available clues for different molecules and solve their molecular structure! One by one, each spectrum reveals information about a molecule, such as the size, the functional groups, and the number of each kind of atom, which can then be pieced together.

Mastering Your Naming Skills
Another important skill in chemistry is naming organic molecules. This can be tricky too, but there is clear method follow. This app will teach you how to name molecules too, as once you have solved the structure of your molecule, you will need to enter the name of the structure into the app.

Challenge Your Friends to a Duel!
In Chemical Detectives you can set up a challenge between classmates and friends. Set the timer, and the number of problems, then GO! You can also choose from easy, medium or hard, which toggles between multiple choice and full text-entry, which is the best way to master your naming skills. Maybe even challenge your teachers!
