Abstract The triplet band d3Δ-a3$\Pi$ (2, 1) of the CO molecule in the near infrared region of 12350--12850cm-1 has been observed and analysed by taking into account the perturbation interaction between the d3Δ(v = 2) and a3$\Pi$ (v = 9) states. The most perturbed lines and most precise perturbation parameters, $\alpha_2$ and $\beta_2$, and electronic perturbation constants, $\xi_{\rm e}$ and $\eta_{\rm e}$ , for the d3Δ (v= 2) and 3$\Pi$ (v = 9) states have been obtained.

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.
