<tr><td colspan="2">Demonstration of the kinetics of series first order reactions. The concentrations of the three components A, B, and C are calculated for the system consisting of two sequential non reversible first order reactions during the specified time period, and the resulting concentrations can be displayed graphically.<br></td></tr>
<tr><td colspan="2">Demonstration of translational speed distributions and their variation with mass or temperature; and Rotational energy level populations and the intensity of pure rotational spectra.<br></td></tr>
<tr><td colspan="2">Calculates from a chemical formula the abundance of each of the isotopic masses and displays the data both as a listing and as a bargraph. This application is used in calculating isotopic distributions for mass spectrometry.<br></td></tr>
<tr><td colspan="2">Calculates molecular weight from molecular formula, and also the mass of the compound corresponding to a selected number of millimoles. The percentage elemental composition can be displayed, and the user may also define their own groups for use in calculations.<br></td></tr>
<tr><td colspan="2">Nuclides is a graphical database showing the Segre chart of over 3000 isotopes of the elements, both stable and radioactive. The segre charts can be plotted colour coded by decay products, halflife, branching ratio, spin, parity, and stability. Decay series for any selected isotope is displayed graphically. Includes decay simulator, an extremely powerful tool, and !Help manual in HTML format.<br></td></tr>
<tr><td colspan="2">A periodic table of the elements is shown in standard format. Clicking on any element opens a window showing various properties of the selected element. The range of properties includes electronic, thermodynamic, and physical.<br></td></tr>
<tr><td colspan="2">RasMol is a molecular graphics program intended for the visualisation of proteins, nucleic acids and small molecules.<br></td></tr>
<tr><td colspan="2">Elements is a graphically based periodic table of the elements showing their properties in graphical form. Over one hundred properties can be plotted such that periodic trends are immediately apparent. In addition, any two parameters can be plotted against each other to show correlations between properties. The isotope section contains details of halflife, abundance, decay mode, binding energy, and many other properties. Includes detailed textual information, spoken pronunciations, and !Help in HTML format.<br></td></tr>
<tr><td colspan="2">Demonstration of the form of the wave functions for the first ten vibrational levels of a harmonic oscillator. You can also plot the square of the wave functions, or show the overlap of the wave functions for two vibrational levels.<br></td></tr>
