Figure 5 is an ORTEP computer plot of the first 50 backbone carbons in a typical chain. Only the fluorine atoms of the sidechains are shown. The various hard sphere exclusions conspire dramatically to keep the fluorines well separated and the chain highly extended even without introducing any external perturbations. The characteristic ratio from the computer calculations is about 11.6 from data for poly(p-chlorostyrene), CR = I l.l, poly(p-bromostyrene), CR = 12.3, and poly(styrene), CR = 10.3 (all in toluene at 30°C), we expect the experimental value for the fluoro-polymer to be in the range of 10 to 12.

Using the computer, plot the titration curve and display it on the computer screen. If possible, print out a hard copy. 

Figure 6.21 Computed plot of the ratio of peak currents, /p(back//p(focwani), against log (kx) for an EC reaction, where t is the time-scale of the CV and k is the rate constant of the first-order homogeneous reaction. Notice how the plot has a similar shape to that shown in Figure 6.20, but the jc-axis is offset by the amount log k.

Drexel undergraduate students in both the lecture and the laboratory of physical chemistry have b n using TKISolver for such calculations as least squares fitting of experimental data, van der Waals gas calculations, and quantum mechanical computations (plotting particle-in-a-box wavefunctions, atomic orbital electron densities, etc.). I use TKISolver in lectures (on a Macintosh with video output to a 25" monitor) to solve simple equations and plot functions of chemical interest.

Empirical analysis of wave motion, fluid velocities. and stress can be made to enable vessel size, configuration and baffle system to be optimized. Analysis of the data Is made by direct visual observation of the fluid motion In the vessel, and computer plotting of wave profiles, fluid velocities, etc.

To answer the question above, whether the observed optical muta-rotation of galactose could be explained by the three-component model constrained to experimental ti/2% the optical rotatory values from the computations listed in Table II were plotted vs. time. The three plots did not differ significantly from each other, in spite of the variation in the ratio ki/ks. The plot for k /kz = 2 is compared with the experimental values in Figure 5. The observed rapid initial drop in rotation is not duplicated in the computed plot. No reasonable combination of...

Figures 14-18 are examples of the computer plots of selected data. These spectra have had dark current and fixed pattern noise subtracted "on-the-fly". (Both of these items are inherent in PDA s, the correction for which represents trivial implementation in terms of software and hardware). In some of the printouts, the individual diode levels can be seen representing 25 urn spatial resolution across the focal plane. The ordinate is quantified to only 12 bits while the PDA s themselves have a dynamic range of 14 bits. This was done for expediencey only.
