Background:
This
organic chemistry learning object 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.
The
spectrocopy 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. In general terms, the problems start easy and gradually get harder as you go, but similar or related problems are grouped together to help the learning process.

We are
working on adding more problems when time allows....
Last
problem update : As of June 18th 2015 there are 56 problems (22 easy, 21 medium, 11 difficult, 2 extreme).
- 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.

- MS, IR and NMR spectra are adapted from SDBS (National Institute of Advanced Industrial Science and Technology, Japan)
- As of 2015, most of the H-NMR and C-NMR are being converted to simulations created using MestReNova.
