The Splatalogue is an attempt to collate, rationalize and extend existing spectroscopic resources for use by the astronomical community. Currently, Splatalogue is a transition-resolved compilation of the JPL, CDMS, Lovas/NIST, and Frank Lovas' own Spectral Line Atlas of Interstellar Molecules (SLAIM). Currently, Splatalogue contains over 3.9 million lines in 720 unique chemical species. Open access starts with splatalogue v.1.0 at www.splatalogue.net.
The Splatalogue effort would not be possible without the efforts of laboratories all over the world. Specifically, you will notice in the last column of any search with Splatalogue, the "LineList" where the data originated. For these data, you will need to reference the following:
Specifically, we would like to give special thanks to H. S. P. Müller, Brian Drouin, John Pearson, Frank Lovas and Floris van der Tak for their continued help and support of this effort. Without their efforts and their input, Splatalogue would not be possible.
Below are listed other sources that may be useful in both obtaining spectral line data as well as collisional cross sections, fitting programs for spectral line data and radiative transfer analysis tools. Use wisely and let us know if you ever find a "broken link" at splatalogue at nrao dot edu.
