These "portable" packages are prime real estate for trojans and keyloggers.
| Software | Main Features | Portable Capability | |----------|--------------|----------------------| | (v1.2‑latest) | • 3‑D molecular editor. • Supports Gaussian input generation. • Real‑time molecular mechanics optimisation. • Extensible via plugins (e.g., orbital visualisation). | Available as a stand‑alone Windows executable ; can be placed on any folder or USB without installation. | | IQmol | • GUI for building Gaussian/ORCA inputs. • Real‑time visualisation of orbitals, densities, and vibrational modes. • Simple batch‑job manager. | Distributed as a portable zip for Windows; just extract and run. | | Jmol/JSmol (web‑based) | • Browser‑based viewer for many file formats (Gaussian log, .cube, .mol). • No installation required; runs via Java (Jmol) or HTML5/JavaScript (JSmol). | Entirely portable – just a folder with the JSmol script. | | Molden | • Classic visualiser for Gaussian output, wavefunctions, and density plots. • Minimalistic UI but very reliable for orbital analysis. | Simple Windows executable; can be copied anywhere. | | GaussView‑lite (unofficial community builds) | • Community‑maintained stripped‑down version that mimics basic GaussView functions. • Caution: not an official product; verify integrity before use. | Often distributed as a portable zip. Check the source (e.g., GitHub) for a trustworthy checksum. | | PyMOL (open‑source version) | • Powerful 3‑D visualisation, scriptable via Python. • Can read Gaussian cube files, render orbitals, electrostatic maps. | Portable installers exist for Windows; also works as a portable Python script. | download free gaussview 5 portable
An open-source Java viewer for chemical structures in 3D, which can read Gaussian output files. It is frequently used for web-based visualizations and can be found at Jmol.org. These "portable" packages are prime real estate for
But while you are optimizing benzene, that portable exe is: • Real‑time molecular mechanics optimisation
: Includes a sophisticated builder to construct molecular systems by atoms, functional groups, rings, or amino acids. Gaussian Integration
: Offers comprehensive support for importing Protein Data Bank (PDB) files and automatically adding missing hydrogen atoms. Vibrational Analysis
GaussView 5 is a graphical user interface (GUI) for Gaussian, a computational chemistry software package used for quantum chemistry and density functional theory (DFT) calculations. GaussView 5 provides a user-friendly interface for building molecules, setting up calculations, and visualizing results.
