=====

RADIS

=====



A code to simulate infrared spectra of molecules.



.. warning::

Deployment is still in progress, not all modules are available yet. The

documentation will be updated as more modules are included.



Documentation

-------------



User guide, install procedure and examples are available on the RADIS Website:



http://radis.readthedocs.io/





Description

-----------



RADIS is nonequilibrium emission and absorption line-by-line code, for use

by infrared spectroscopic that want to compare line databases, or experimentalist

that want to fit their experimental line-of-sight spectra.



Written as a general purpose radiative solver, the code is built around the HITRAN,

HITEMP and CDSD databases for molecules in their electronic ground state. Energy

levels are read from tabulated databases or calculated from Dunham developments.

Boltzmann, Treanor, and state specific vibrational distributions can be generated.

A modular architecture makes it possible to add new species without modifications

to the core code. Thus far, |CO2|, CO are featured for non-equilibrium calculations,

and all species present in the HITRAN database are featured for equilibrium

calculations. To fit experimental spectra, RADIS includes a line survey tool, an

interface with a look-up database to improve fitting convergence times, and a

multi-slab module with a radiative transfer equation solver to reproduce line-of-sight

experiments. Validation cases against existing spectral codes and experimental

results from various plasma sources are included.





Examples

--------



A `3-temperature fit <http://radis.readthedocs.io/en/latest/#multi-temperature-fit>`_ built on top of RADIS.
