The main goal of the project is to facilitate the access to the spectroscopic data obtained by (or in collaboration with) our research group at PhLAM Laboratory, University of Lille. Lille Spectroscopic Database (LSD) is a complementary tool to the well known resources like JPL catalog, and Cologne Database for Molecular Spectroscopy (CDMS). While the great majority of the data from our group is directly available as supplementary material to our publications, LSD is an additional tool providing more versatility in the data access.
Lille Spectroscopic Database is created and maintained by Roman Motiyenko and Laurent Margulès
Data can be accessed using standard web interface: by entry or by search form. For non web applications, a set of API functions may be used. A search bar in the navigation menu may be used to search database entries by their chemical name or formula or to launch a rapid search by frequency.
The data from table can be downloaded in a .zip archive containing 3 files:
.catformat file with predicted spectra
.catfile can be generated with the following options:
Most of the molecular spectra are predicted using the programs and models that are not compatible with SPFIT/SPCAT
quantum numbers formats. For each table, the information about quantum numbers is provided in
as well as online. For further details, see Quantum Numbers Formats section.
