Iconicity

Plenary 18. Robin J FI Clark, e-mail address r.i.h.clark ucl.ac.uk (RS). Reports on recent diagnostic probing of art works ranging from illuminated manuscripts, paintings and pottery to papyri and icons. Nondestructive NIR microscopic RS is now realistic using CCD detection. Optimistic about new developments. 

In order to allow any multiple chlorination of the biphenyl skeleton, the user may define an atom list (eonsisting of hydrogen and chlorine atoms) and substitute all H-atoms by this list. One may click on the drop-down selection box behind the element icons, select the options Generics. .set the user-defined atom to A1 and quit by the OK button. As a result this atom selection is active for the subsequent drawing steps. After this atom list is drawn ten times as the ten substituents, its composition has to be defined by clicking the A, icon on the left-hand side of the structure editor and by selecting H and Cl in the periodic table (Figure 5-16). 

Besides these main categories, a large number of hybrid visualization techniques also exist, which arc combinations of the methods described. Well-known hybrid approaches arc the 2D or 3D glyph displays. These techniques combine the multidimensional representation capabilities of icon-based methods with the easy and intuitive representations of scatter-plot displays, Therefore these techniques can also be frequently found within chemical data analysis applications. 

Figiu e 9-33 shows the three major visualization techniques geometric display, icon-based display, and hierarchical display, as well as the hybrid technique with 3D glyphs.

View the contour map m several planes to see the general Torm of the distiibiiiioii. As long as you don t alter the molecular coordinates, you don t need to repeat th e wave function calculation. Use the left mouse button and the IlyperChem Rotation or Translation tools (or Tool icons ) to change the view of amolecnle without changing its atomic coordinates.

As you go through this text you will see two dif ferent modeling icons The SpartanBuild icon alerts you to a model building opportunity the SpartanView icon indicates that the Learning By Modeling CD includes a related model or animation... 

SpartanBuild is intended both to assist you m solving problems m the text (these problems are matched with the following icon)... 

SpartanView models are intended to give you a molecule s eye view of chemi cal processes and to help you solve certain text problems The text uses the following icon to alert you to corresponding models on the CD... 

Each icon corresponds to a model or a group of models on the CD All of the mod els for a given chapter are grouped together m the same folder For example the mod els for this appendix are grouped together m a folder named Appendix The location... 

The Learning By Modeling CD ROM developed by Wavefunction Inc in connection with the fourth edition of this text accompanies the fifth as well We were careful to incorporate Spartan so it would work with the textbook—from the Spartan images used m the text to the icons directing the student to opportunities to build models of their own or exam me those m a collection of more than 250 already prepared ones... 

In collaboration with Wavefunction we have created a cross function CD ROM that contains an electronic model building kit and a rich collection of molecular models that reveal the interplay between electronic struc ture and reactivity m organic chemistry Icons m the text point the way to where you can use this state of art mo lecular modeling application to expand your understand mg and sharpen your conceptual skills...

Clieking on the El icon attaehed to SIMULINK lists the SIMULINK options, and E Continuous lists the eontinuous systems options. To obtain a transfer fune-tion bloek, eliek and hold left mouse button on the Transfer Fen ieon under Continuous , and drag to untitled window. 

Visit http //wwwl.fishersci.com/catalogs/. This site is the Fisher Scientific online catalogue. Once connected, double click on the Catalogue. Double click on the Fisher Chemical catalogue. Then select the alphabetical group containing your chemical s name or type in the product in the Search box. When you find the chemical of interest, scroll down and click on the MSDS icon found within the other product information for the chemical. 

Once you have completed the installation procedure you can run the program by selecting the MEN program icon from the Start Menu (Windows 95) or from the program group (Windows 3.1). 

I am writing this book using WordPerfect 6,1 in Windows 3.1, I found it convenient to make an "FTAP.bat" file to exit using the MSDOS icon and then type "FTAP" to see the main menu for FTAPSUIT.
