Analysis and Export
Taking Measurements
Click atoms in the viewport to select them, then read off the geometry:
| Atoms selected | What you see |
|---|---|
| 2 | Distance (Å) |
| 3 | Bond angle (°) |
| 4 | Dihedral angle (°) |
Hold Shift and click to add atoms to the current selection.
Display Options
Use the display controls to change how the structure is rendered:
- Van der Waals spheres — space-filling view, useful for inspecting steric contacts
- Show hydrogens — toggle hydrogen visibility on and off
- Convex hulls — highlight detected aromatic or ring-like regions when available
- Conformer overlay — compare multiple geometries at once
- Stereochemistry labels — show stereochemical assignments when annotated data is available
- Non-covalent interactions — show contact annotations when the data is available
- Mulliken charges — color atoms by Mulliken partial charge and show a matching legend when supported QM output is loaded
- COSMO surface — render a solvation surface when compatible data is loaded
- Volumetric surfaces — toggle cube-derived HOMO, LUMO, density, and ESP datasets individually when present
- Force arrows — display force vectors on atoms after a single point energy calculation
- TS analysis bonds — highlight bonds being formed or broken in a transition state
- Auto-rotate — continuous rotation for presentations, with vertical and diagonal options
Cube Surface Visualization
When Gaussian cube data is loaded, the viewer adds a dedicated surface control block and renders each supported dataset as its own overlay layer.
Supported cube-derived views:
- HOMO / LUMO — positive and negative orbital lobes
- Density — electron density isosurface
- ESP — electrostatic potential mapped onto a surface, ideally using a matching density cube
Viewer behavior:
- Each available cube dataset gets its own display toggle.
- ESP surfaces show a matching color legend in the viewer.
- The same upload can expose multiple datasets at once when related cube files are provided together.
Molecular Information
The viewer displays key properties of the loaded structure:
- Chemical formula — composition of the current geometry
- SMILES — canonical SMILES string with a copy button
- Charge and multiplicity — shown when set
- Point group and symmetry number — shown when symmetry metadata is available
Structure History
Recent structures are stored in the browser so the viewer can restore where you left off. This is useful when switching between loaded files, edited geometries, and newly computed results within the same session.
Exporting
Geometry Export
Export the current geometry when you want to save it or use it in another tool.
| Format | Extension |
|---|---|
| XYZ | .xyz |
| CIF | .cif |
| SDF / MOL | .sdf, .mol |
| PDB | .pdb |
| VASP | .vasp |
| Cube | .cube |
Available export formats depend on what is currently loaded.
Image Export
Save the current 3D view as a PNG or GIF image using the save image button.
Share Link
Generate a shareable URL that encodes the current structure so others can open it directly in the viewer.
The Share button opens a small menu with three one-click options:
- Copy link — copies the direct share URL
- Embed as badge — copies a branded badge snippet that links back to the shared view
- Embed as viewer — copies an iframe snippet for embedding the interactive branded molecule viewer on a web page
Example Badge
Markdown
Use this in README.md files, issues, pull requests, and other Markdown surfaces:
[](https://atomiverse.com/viewer?share=YOUR_SHARE_ID)
HTML
Use this on any web page:
<a href="https://atomiverse.com/viewer?share=YOUR_SHARE_ID" target="_blank" rel="noopener noreferrer">
<img src="https://atomiverse.com/assets/atomiverse-share-badge.svg" alt="View on Atomiverse" height="20">
</a>
Replace YOUR_SHARE_ID with the share ID created by the viewer. The built-in Embed as badge action copies a ready-to-paste version automatically.
Embedded Viewer
Use this on any web page when you want to showcase an interactive shared structure inline:
<iframe
src="https://atomiverse.com/viewer?share=YOUR_SHARE_ID&embed=1"
title="Atomiverse molecule viewer"
loading="lazy"
referrerpolicy="strict-origin-when-cross-origin"
allow="fullscreen"
allowfullscreen
style="width:100%;height:420px;border:0;border-radius:18px;overflow:hidden"
></iframe>
The built-in Embed as viewer action copies a ready-to-paste version of this snippet automatically.
