Notes. The frequency, upper energy (E_up/k), Einstein coefficient (A_ij) and upper state degeneracy (𝑔_up) are marked. The values for A_ij are written in the form of x(−a) = x × 10^−a. The molecular are properties are from the JPL (Pickett et al. 1998) and CDMS (Müller et al. 2001) spectroscopic catalogues, as noted.

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.
