Chemianence runs a hybrid quantum-classical simulation engine that solves the time-independent Schrödinger equation using density functional theory approximations. The computational kernel leverages GPU acceleration for matrix diagonalization, enabling real-time calculation of electron density distributions for molecules containing up to 200 atoms with 6-31G basis sets.
The molecular dynamics integrator implements a velocity Verlet algorithm with adaptive timesteps, automatically adjusting integration precision based on energy conservation thresholds. Force field calculations use a combination of bonded potentials derived from quantum mechanics and non-bonded interactions computed through Lennard-Jones and Coulomb terms with particle mesh Ewald summation for long-range electrostatics.
Visualization rendering occurs through a custom WebGL pipeline that constructs isosurfaces from volumetric electron density data using marching cubes algorithm. The system supports real-time orbital manipulation with interactive cross-sections, allowing users to explore HOMO-LUMO gaps and molecular orbital symmetries through touch gestures with sub-50ms latency on modern mobile GPUs.
Built-in Hartree-Fock and DFT solvers calculate ground state electronic structures with B3LYP, PBE, and M06-2X functionals. Supports single-point energy calculations, geometry optimization with BFGS algorithm, and vibrational frequency analysis for thermodynamic property prediction at various temperature conditions.
Run NVT and NPT ensemble simulations with Nosé-Hoover and Berendsen thermostats. Trajectory analysis tools compute radial distribution functions, mean square displacement for diffusion coefficients, and hydrogen bond statistics. Export trajectories in XYZ and PDB formats for external analysis.
Real-time rendering of molecular structures with ball-and-stick, space-filling, and ribbon representations. Visualize electron density isosurfaces, electrostatic potential maps, and molecular orbitals with customizable isovalue thresholds. Multi-touch gestures control rotation, zoom, and orbital phase visualization.
Simulate IR and Raman spectra from calculated vibrational modes with intensity predictions based on dipole moment derivatives. UV-Vis absorption spectra generated through TD-DFT calculations with up to 50 excited states. Export spectra data in CSV format for publication-ready plotting.
Construct molecules from scratch with intelligent bond formation based on valence rules and hybridization detection. Import structures from SMILES strings, PubChem CID lookup, or PDB database with automatic protonation state assignment. Fragment library includes 200+ common functional groups and ring systems.
Locate transition states using nudged elastic band method and dimer algorithm. Calculate activation energies and reaction rate constants through transition state theory. Visualize reaction coordinates with animated molecular motions showing bond breaking and formation processes along minimum energy paths.
