The three tabs at the top of the compound window select different views as described below.

Library view

In Library view a list of all the compounds in the SpectraSchool library is displayed. Please note: from version 3 onwards the list of available compounds is determined by the learning level chosen on the home page. Clicking the compound name will plot its spectra and also display the Detail view for that compound (described below). The buttons to the right of the compound name have the following function.

Button
Description
Overlay
Overlay spectra. The compound's spectra are added to the graph, overlaid with any existing plots.
Replace
Plot single spectra. Any existing plots are removed and the compound's spectra are plotted alone.
Minus
Remove spectra. Remove the compound's spectra from the graph.
Identify
Identify the compound. In problem-solving mode this replaces the above three buttons. Press to identify the unknown compound.
Popup
Display pop-up datasheet.

A limited number of compounds have 'hotspots'. These are areas of the spectra which when clicked display an image or animation illustrating the structural origin of the peak in question. These compounds are indicated with a Hotspot icon in the library view.

Searching the library

The controls at the bottom of the compound window may be used to search the library. Choose a chemical family and enter a complete or partial compound name and matching compounds are listed above. The buttons in this function as follows.

Button
Description
family
Use this menu to restrict the search to compounds matching the
Search
Searches the library for compounds matching the selected family and the name entered in the name box. Pressing return has the same effect.
Clear
Restore the family menu to all famillies and clear the name box, restoring the full library list at the selected learning level.
Print
Print the current compound window view.
Help
Display this help.
level
This displays the learning level selected on the home page, which controls the list of available compounds.

Detail view

In Detail view a datasheet for the selected compound is displayed. If your version of Java permits it, this will include a rotatable 3D structure. In addition, the Library view plotting controls are shown together with an extra row of buttons to set the plot colour for this compound's spectra.

Clicking a compound name in the graph is another way of showing Detail view for that compound.


Identify view

Switch to identify view and follow the on-screen instructions to enter problem-solving mode, in which your mission is to identify an unknown compound from an analysis of its spectra.

In problem-solving mode the plot buttons described above are replaced with the Identify button , which is pressed to identify the unknown compound.
