Properties of Substances, Chemicals

For more than 2500 substances in the gaseous, liquid or solid state
are thermochemical, spectroscopic, and other chemical and physical properties available.

Mainly spectroscopic and thermochemical properties are evaluated by scientists.
The data is self consistent and most results are published in international journals, too.

Available properties were delivered by email, free of charge for academic usage without commercial background, after request to info "at"

For comparison, experimental and/or calculated data available in literature are given, too.

Identification of substances through:

- CAS number
- Chemical Formula
- 3-dimensional chemical structure
- Names (IUPAC-Standard- and Trivialnames)

The following evaluated values are available:

- UV-, VIS, IR-, Raman- and NMR-spectra
- Vibration frequencies

- Rotational constants A, B, C
- Moments of Inertia I
- Dipolmoments
- Polarizability

- Standard enthalpy of formation at 0 K, and at 298 K,
- Entropy
- Heat capacity at constant pressure and constant volume
- temperature dependent calculations of:
- Enthalpies
- Entropies
- Heat capacities

Thermochemical properties will be provided in so called 7- and 9-term polynom NASA format for easy use in modelling and CFD programs, like Cantera (R), Chemkin (R), Cosilab(R), Homrea(R), CFX(R),Ansys(R), Fluent(R).
