Abstract The Doppler-free optical-optical triple-resonance(DF-OOTR) spectroscopy and its line-shapes have been studied in detail theoretically and experimentally. The line center, linewidth and lineshape of an isolated DF-OOTR spectra component have been derived by using density matrix motion equation describing the interaction of a three-level system with three optical fields. The variations of the lineshape symmetry, the relative position and the strength of the Doppler-free Lorentzian dip to its background are comparable to the experimental traces varying with the relative intensities of the two mutual-saturating probe laser beams, as well as with the detuning of the first pumping laser from the intermediate level. The DF-OOTR technique shows a distinguished advantage especially in the labeling of the transitions and in the determination of absolute position of the upper level affected by perturbation shift, as these happened often in the dense molecular highly excited states.

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.
