Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
We study the ability of the energy corrected sudden (ECS) scaling law associated with a hybrid exponential-power (EP) fitting law for the basis rate constants to model the rotational dependence of isotropic Raman linewidths. We determine the temperature dependence of the hybrid law (EP) parameters and give several applications for various molecular collisional systems over a wide temperature range. In particular, we find that the ECS-EP law gives a very good description of both rotational and temperature dependences of the Raman line broadening coefficients of N perturbed by HO contrary to the ECS-P law. For all the collisional systems studied the ECS-EP law is found very suitable to describe the line broadening coefficients. We give a complete set of ECS-EP parameters for these collisional systems which play an important role in coherent anti-stokes Raman spectroscopy thermometry. We also test the ability of the ECS-EP law to predict accurate collapsed Q branch at high density. An application performed on the Raman Q branch of pure N at high density demonstrates that the ECS-EP law properly models the rates of state-to-state rotational energy transfer. The overall collisional line shift obtained from the collapsed Q branch is in perfect agreement with low pressure measurements on isolated lines. © 1990 American Institute of Physics.
