Get started with DiChem to explore the interactive periodic table, browse the most exhaustive diatomic spectroscopic database available, create custom plots in seconds, and predict properties of new diatomics with our AI predictor. DiChem turns complex spectroscopic data into actionable insight—faster, clearer, and more reliably than traditional workflows.
DiChem
For professors and researchers
Molecule mode: The Most Exhaustive Diatomic Spectroscopic Database: Access a curated, referenced collection of spectroscopic constants (Te, ωe, ωexe, Be, αe, Re, dipole moment, ionization potential, term symbols, and more)of diatomics. Each data point is provided with the literature sources, so you can trust and cite the values. Replace hours of literature searching and manual plotting with instant, organized access to vetted constants and visual tools.
AI mode: Propose a novel diatomic combination; our machine learning model returns predicted spectroscopic constants and confidence intervals tailored to your desired electronic state. The tool leverages patterns across experimental data and computational descriptors to provide rapid, physically consistent estimates—useful for planning experiments, screening candidates, or guiding computational work.
For students and teachers
Atom mode: Pick any of the elements of the periodic table and learn from it. Quickly compare element properties side-by-side and use filters (mass, electronegativity, ionic potential, etc.) to isolate trends relevant to bonding and spectroscopy. Select a bunch of elements and plot their properties with our plotting tool to elucidate the periodic trends hidden in the structure of the periodic table.
Game mode: Test your knowledge with our Trivia for atoms and molecules. With this tool, you will always be ready for the exams. Nothing will stop you from learning the secret life of atoms and molecules.
Molecule mode: After selecting two atomic elements, DiChem presents all the spectroscopic constants needed to understand the molecule’s basic spectroscopic fingerprint. When a molecule is observed, DiChem displays the experimental values of the spectroscopic constants, along with the associated references. If a molecule has never been synthesized, no problem, our AI will give you a prediction with an uncertainty errorbar to assess the quality of the prediction.
