The NASA Ames PAH IR Spectroscopic Database   (PAHdb) hosts the world’s foremost collection of infrared (IR) PAH spectra. PAHdb’s spectral libraries contain over 4,000 laboratory measured and quantum chemically computed PAH spectra. Beyond spectroscopic data, PAHdb also provides the models and software tools to work with the spectral data. The portal to the data and tools is the PAHdb website, which is located at https://www.astrochemistry.org/pahdb.
The pypahdb Python package is being developed as part of the awarded James Webb Space Telescope (JWST) Early Release Science (ERS) program “Radiative Feedback from Massive Stars as Traced by Multiband Imaging and Spectroscopic Mosaics” (program website; ID: 1288). The program is coordinated by an international “Core team” of 19 scientists and supported by 119 “science collaborators”. Pypahdb is developed by the NASA Ames PAH IR Spectroscopic Database team, asscociated with the Astrophysics & Astrochemistry Laboratory at NASA Ames Research Center.
