About this Site
This online workbook has been developed for senior undergraduate
and graduate students learning to solve the structures of organic compounds
from spectroscopic data. Most problems contain an IR spectrum (film or
KBr pellet), a 500 MHz 1H NMR spectrum, a 125 MHz 13C
NMR spectrum, and a 70 eV electron ionization Mass Spectrum. In the 1H
NMR spectra, the phrase "exchanges" means that shaking the NMR solution
with D2O resulted in loss of the signal
due to H/D exchange.
How to Use this Site
To begin solving problems, simply select "Problems" from
the left frame. This will display a table of problem numbers. Select a
problem number from the table, and a menu will appear in the left frame.
Choose an item from this menu to display a spectrum, return to the table
of problem numbers, or return to the table of contents. NOTE:
most of the NMR spectra are image mapped; clicking on a mapped region of
a spectrum will display an enlargement of that region.
If you have questions or if you're stuck, feel free to click the "Ask Dr. Structure" image in the left frame to shoot Dr. Structure an email.
This site has been optimized for WWW browsers which support
tables, frames, and client-side image maps. It is best viewed from monitors
15" and above operating at resolutions of 800 X 640 pixels or higher. Printing
spectra displayed on the screen will result in a low resolution hardcopy.
High resolution (300 dpi) spectra will be made available for ftp at a later
date. Until then, remember that this site is intended to be used as an
