Notes. All transitions listed are in the ground vibrational state. For lines with hyperfine components, only the frequency of one of the components has been listed, but the integrated intensity given has been summed over all detected components. The values in parentheses denote the total uncertainty in the integrated intensity, including the 20% uncertainty in the flux calibration.
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.
