KIDA   KIDA is a database of kinetic data of interest for astrochemical (interstellar medium and planetary atmospheres) studies. In addition to the available referenced data, KIDA provides recommendations over a number of important reactions.

Chemists and physicists can add their data to the database through several paths listed here.
Astrophysicists can download the database through the download form. You need to log in to add or download data. Forms below allows to consult and download the data.

New rate coefficients and reactions for the HCN and HNC chemistry in the cold ISM have been added from Loison et al. (2014)

New data

New data

New reactions and/or rate coefficients proposed by Loison et al. (2014) for carbon chemistry have been added.

Search by species
Species*
Formula (isomers) Exact formula Inchi code


Ex : H2O, NaOH, C+ , InChI=1S/OS/c1-2
Warning : Second letter of 2-letters elements have to be lowercase, eg Na
Search by element
Species contains the element *
positive ion negative ion neutral


Ex : C will search for all species with C atoms
Ex : O H will search for all species with O or H atoms
Ex : OH will search for all species with O and H atoms
Warning : Second letter of 2-letters elements have to be lowercase, eg Na
Indicate a species (ex: CH, H3O+) or a couple of species (ex: C + H2)
Warning : Second letter of 2-letters elements have to be lowercase, eg Na
Search in Isomers Exact formula (needed for l- and c- forms)
