Spectroscopy problems.

Electromagnetic spectrum

At this stage, a number of examples of different types of spectral data can be displayed with JSpecView by selecting from the different list boxes.
Download this information for known materials to see how they compare with what you expect.

Examples of the combination of spectra and molecular graphics to show the interpretation of simple IR, MS or NMR using JSpecView and Jmol are available.

Sample files in JCAMP-DX format can be found in the testdata section (some showing typical errors encountered).

An introduction to the use of IR, NMR and MS instruments is available from the RSC. Take a look at the on-line problems and the video clips (~80-100 MB each).

For the C32J organic laboratory class, the unknown samples are here for you to identify.

Some sample JCAMP-DX files:
FTIR UV/Vis

GC MS

H NMR

EPR
