Notes. Overview of the identified molecular transitions in the Lagoon Nebula. Frequency, upper-level energy Eup, spontaneous emission Einstein (A) coefficient Aij and upper-level degeneracy gup are listed for each transition according to the values stated by the database given in the last column. The frequency uncertainty for each transition is given in parenthesis in units of kHz and was rounded to integers. Partially blended transitions are indicated with superscript markers a) to u). The full table with all transitions is available at the CDS.
