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
Changes in the Raman spectra of N, H, and CO are studied in the range of 200–3800 cm depending on the concentration of surrounding CH molecules at a fixed medium pressure of 25 atm and temperature of 300 K. It has been found that changes in the spectral characteristics of purely rotational H lines in a CH medium are negligible, while the Q-branches of the v/2v Fermi dyad in СO become narrower and wavenumbers of its high-frequency component and v band of N decrease. In addition, under these conditions, the ratio of intensities of the CO Fermi dyad Q-branch varies in proportion to the concentration of surrounding molecules of CH. The obtained data will be used in diagnosing the composition of natural gas using Raman spectroscopy.
