Do you teach organic spectroscopy and/or qualitative analysis?
If so then you might be interested in the Windows program
WinTorg, version 3.2 of which has just been released.

WinTorg simulates the process of identifying unknown organic
compounds.  It is suitable for use by early university or college level
students. Spectroscopy  is emphasised. There are 100 compounds
each  having pmr, cmr, ir, ms spectra and uv data together with
other  information. The unknowns can be identified by spectroscopy
alone or in combination with chemical tests.

WinTorg is easy to use, has extensive help available and can be
customised.  Student progress is recorded and reported.

A free demonstration/shareware version (having only 3 compounds)
is available.  For more details see

Registered users of WinTorg who purchased the program within the
last 12 months can obtain a free upgrade on request.
