List of Species and Transitions currently recognized by the database.

Use your browser's string searching function (e.g. on NCSA Mosaic, the Control-S key sequence or "Find in Current" menu item) to locate a species of interest. Quantum number notation is preferred for transitions; molecular transitions follow the notation given by Lovas, Snyder, & Johnson (1979, ApJS, 41, 451).

Note that this list is in alphanumeric order such that "12CO" comes before "CO".
