Notes.
(a)
The frequencies for the lines were obtained from the Cologne Database for Molecular Spectroscopy (CDMS, Müller et al. 2001, 2005), except for NH3 lines whose frequencies were obtained from the JPL Molecular Spectroscopy database (Pickett et al. 1998).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
