Interactive Spectroscopy Problems

Last content update July 2009

Start from question:

Background:

This learning tool allows you to work through a set of spectroscopy problems using an interactive drawing tool. After each attempt, your structure is assessed and you are given feedback to help you work towards the solution. Hints are available in many cases and worked solutions are provided.

In order to use this material you need JAVA enabled on your computer, a simple automatic check indicates that

The current version works in the common browsers like Flock, Firefox, Mozilla, Internet Explorer and Netscape.

(note : in May 2009, an Internet Explorer problem arose that we believe is now fixed)

The problems:

Each problem contains spectral data (mass spectrum, infra-red, ¹³C-nmr and H-nmr) for an unknown compound.
You are required to deduce the structure of the unknown compound that is consistent with all the data provided.
Some "general" hints are available to encourage you to look for the right information and to try to get you going. In addition, an online "tutor" will give you feedback on any wrong answers you submit. The problems start easy and get harder as you go.

We are working on adding more problems.

Last problem update : July 2009 contains 27 problems, mainly easy.

Use the buttons to show the spectra
Draw your answer in the window in the left and submit it.
Review the feedback in the middle column.
Hints are available after you have made 3 attempts
A worked solution is available after 8 attempts.
The score per question is given when you get the answer, it is based on the number of attempts and how many hints you use. When you exit, you will be given your overall total.
