WebMO MO Viewing Help

Getting Started

WebMO Pro allows the viewing of molecular orbitals on Windows/PC clients through the use of a separate MOViewer application. This application must be installed locally on the client before WebMO's MO viewing features can be utilized.

Installation

To install MOViewer, first download MOViewer Setup program and save the file to disk when prompted. When the download completes, run the setup program to begin the installation process.

When the setup program appears, click "Next", read and agree to the terms of the license agreement, select an installation location, select a "Typical" installation type, and wait for the installation to complete. If necessary, restart when prompted.

Viewing Molecular Orbitals

After completing a "Molecular Orbital" calculation using any computation engine, view the completed job; the molecular oribitals are listed near the end of the "View Results" page. Click the "View" button next to the orbital you wish to view.

The orbital will open in the external MOViewer application. The orbital picture can be manipulated using mouse commands similar to the WebMO editor; left-click and drag to rotate, right-click and drag to zoom. For calculations such as ESP or homo/lumo density, where a color-gradient is mapped on a surface, blue represents high values, which blue represents low values.

A variety of preferences for the orbital can be altered from the Edit:Preferences dialog. In particular, the number of grid-points can be altered to obtain a higher resolution orbital, or increase the rendering/calculation speed.

Internet Explorer users
When prompted to save the resulting .MO file, you may choose either "Save this file to disk" to save the orbital to be viewed at a later time, or "Open this file from its current location" to open the file in MOViewer. Select Open to open the file in MOViewer.

Netscape users
The first time you attempt to view an orbital, Netscape will return an "Unknown file type" prompt. Select "Pick App..." and browse to and select the MOViewer executable (MOViewer.exe) located by default in C:\Program Files\MOViewer. When prompted to save the resulting .MO file, you may choose either "Save it to disk" to save the orbital to be viewed at a later time, or "Open it" to open the file in MOViewer. Select Open to open the file in MOViewer.

Automatically opening MO's (helpful hint)
To automatically open the orbitals in MOViewer, simply choose "Open" and unselect the "Always ask before opening this type of file" option at the bottom of the dialog. This will cause .MO files to be opened automatically without further prompts.
