Abstract The laser-induced fluorescence excitation spectra of jet-cooled CuF have been recorded in the range of 19000－21470cm$^{-1}$, in which the CuF radicals were produced by the reaction of SF$_6$ with copper atoms from a dc discharge-sputtering source under supersonic jet conditions. Eight observed vibronic transition bands have been assigned as the transition from the ground state $X(^1\Sigma^+$) to $B(^1\Sigma^+$), $C(^1\Pi$) and an unreported upper state. The rotational structure of all observed bands has been analysed at the estimated rotational temperature 80K. We determined the newly observed band to be the ($^1\Pi, v=1)－X(^1\Sigma^+v=0$) transition according to the character of the rotational structure and the isotopic shift analysis. In addition, the lifetimes of the states involved in these bands were measured.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
