Abstract A four-parameter nonlinear model is introduced to the description of the X-Y stretching modes of XY6 octahedral molecules in the electronic ground state. We here only apply it to the calculations of S-F stretches of SF6 molecule. The model calculations appear to describe the observed data well, and predict some new vibrational bands at accurate energies not yet observed.

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.
