Abstract Quasi-classical trajectory (QCT) calculations are employed to study the dynamic properties for H(D) + OF reactions on the adiabatic potential energy surface (PES) of the 1$^{3}$A$''$ triplet state. Obvious differences between the reaction probabilities for $J = 0$, integral cross sections for $J \ne 0$, branch ratios of the product and internuclear distances as well as product rotational alignments between the title reactions are found. These differences are attributed mainly to the different reduced masses of the reactants and the different zero-point energies (ZPEs) of the transition state.

Online attention
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.
