Leiden Ice Database for Astrochemistry
IR spectra and optical constants measured in the Leiden Laboratory for Astrophysics
The Leiden Ice Database for Astrochemistry (LIDA) contains the infrared spectra of a massive number of astrophysical ice analogs at different temperatures and chemical environments. The data stored in this database have served the astronomical ice community since the 80's that helped to successfully interpret the observations carried out by ground- and space-based telescopes.
Analysis of many observations from the James Webb Space Telescope (JWST) have used the data available in LIDA. In particular, the JWST Early Release Science program called ICE AGE and the JOYS programs. You can visualize the LIDA citations here.
In this website, you will find public and comprehensive number of IR spectra and optical constants of astrophysical ice analogues, as well as online tools to support the ice spectral analysis of astronomical observations.
The construction of LIDA was a dream of Prof. Harold Linnartz (in memoriam), who unexpectedly has passed away on December 31st 2023. Prof. Linnartz was Director of the Leiden Laboratory for Astrophysics and was well known for his research on 'unlocking the chemistry of the heavens'.
