Notes. (a)Estimated measurement uncertainties for each data group. (b)Number of lines (left part) or transitions (right part) of each category in the least-squares fit. Note that due to blending 10 275 measured line frequencies correspond to 12 641 transitions in the fit. (c)Root-mean-square (RMS) deviation of corresponding data group. (d)Upper and lower state torsional quantum number vt. (e)Weighted root-mean-square (WRMS) deviation of corresponding data group.
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.
