Molecular Structure Calculations (1050 small molecules, ions, and radicals)

Solve the Secular Equation HΨ = ESΨ

The Secular Equations applet solves the generalized eigen value problem, which is used for Extended Huckel Molecular Orbital calculations. Instructions for the Secular Equations Solver cover two examples, LiH and CH₄.

CNDO Molecular Orbital Program

Complete Neglect of Differential Overlap:
CNDO Molecular Orbital Applet with forms based input.
CNDO Molecular Orbital Applet with text file based input.

Mopac Molecular Orbital Program

You can download the executable file for the OS-X version of Mopac 7 from WebMo.net (or the old Power PC version of Mopac 6.)
Here is a test data file for BF₃ to check out MOPAC. Cut and paste this data into a Word document and then save the document in "text only" format (with "LF only" for OS-X). Here are some instructions on how to use MOPAC to do calculations on diatomic molecules. into a Word document and then save the document in "text only" format (with "LF only" for OS-X). Here are some instructions on how to use MOPAC to do calculations on diatomic molecules. Cut and paste this data into a Word document and then save the document in "text only" format (with "LF only" for OS-X). Here are some instructions on how to use MOPAC to do calculations on diatomic molecules. Here is a data file for linear ozone.

You can download the executable file for the Windows version of Mopac 6 or MOPAC 7 (from www.webmo.net) or MOPAC 7 (from CCL)

Here is an application to help you write the input file for MOPAC calculations. You can run it from our web site or please feel free to copy the source to your own computer. If you copy the application to your own system, you can run it by opening the "zmatrix.html" file from the browser menu.

MM3-Molecular Mechanics

Build the 3D-structure of a molecule, predict the enthalpy of formation, and the normal modes of vibration. Run an MM3 molecular mechanics calculation: web-MM3 (The old Marvin-only version is MarvinMM3d )

Units Conversions

Here is an energy conversion application that you will find helpful, especially for converting Hartrees and eV to kJ/mol.

Spectroscopy Tools

The NMR Course Homepage has many useful resources in spectroscopy.

NMR and IR:
JCamp NMR and IR Spectrum Viewer (Spectra files with a ".dx" or ".jdx" extension)(Requires IE-11 or a recent version of Safari)

Mass Spectrometry: The Fragment Finder finds the possible formulas that match a given molar mass. Then the M+1 and M+2 ratios and the exact masses of each of the possible fragments is calculated.
Formula Finder finds the possible formulas that match a given molar mass and several fragments. Then the M+1 and M+2 ratios and the exact masses of each of the possible fragments is calculated.
Isotope Cluster calculates the isotope pattern for a given molecular formula. It includes 3rd and 4th period representative and transition metal elements.

Dynamic NMR: Exchange: Chemical Exchange Lineshape Simulation for 2 site exchange. If you don't want to use the DHTML version use Exchange (low resolution graphics) for Internet Explorer.

Group Theory: ABC is an applet that calculates the point group for a molecule.

Statistical Mechanics:

ABC is an applet that calculates the point group, Principal Moments of Inertia, Rotational Constants, and Entropy of Rotation of a polyatomic molecule.

Equilibrium Constants from Molecular Structure is an applet that uses statistical mechanics to calculate the equilibrium constant for a simple bimolecular chemical reaction involving diatomic molecules and atoms. Equilibrium Constants for Polyatomics is for reactions involving polyatomic molecules.

Kinetics

The Kinetics Mechanism Simulation application integrates the rate laws for a mechanism with up to four reversible steps. A short tutorial-style introduction will help you get started. Some examples are also available.

The Classical Trajectory Reaction Dynamics applets calculate trajectories for the endothermic-late barrier H + HF and the exothermic-early barrier H + HBr reactions.

Excel Spreadsheets

Here are some Excel examples for A General Approach for Calculating Speciation and Poising Capacity of Redox Systems with Multiple Oxidation States. These programs calculate the redox speciation, titration curves, and pe-pH diagrams for most redox systems.

General Resources

Uncertainty Calculator does propagation of errors calculations for any equation.

Nonlinear Least Squares Curve Fitting does curve fits for a variety of useful equations and gives the uncertainty in the fit parameters. A 4-parameter version is also available.

Matrix Diagonalization The eigen JavaScript application diagonalizes real, symmetric matrices. This application is useful for Huckel molecular orbital calculations. Huckel Molecular Orbital Instructions are available.

HTML Editor is a JavaScript based HTML editor that you can use to design your own web pages.
LetrSet is a JavaScript based HTML type setter that you can use to add faⁿcy headings to your own web pages. A page of examples is available in the LetrSet Gallery.
