Co‐saved, co‐tweeted, and co‐cited networks [PDF]

open access: yesJournal of the Association for Information Science and Technology, 2018
Counts of tweets and Mendeley user libraries have been proposed as altmetric alternatives to citation counts for the impact assessment of articles. Although both have been investigated to discover whether they correlate with article citations, it is not known whether users tend to tweet or save (in Mendeley) the same kinds of articles that they cite ...

High‐resolution stimulated Raman spectroscopy of low‐frequency rotational transitions: Obtention of collisional broadening coefficients in the rotational S branch of CO perturbed by H2

open access: yesJournal of Raman Spectroscopy, Volume 54, Issue 10, Page 1099-1113, October 2023., 2023
This paper demonstrates the application of high‐resolution quasi‐continuous stimulated Raman spectroscopy to the study of low‐wavenumber rotational transitions, down to ~11.5 cm−1. With this capability, we have been able to measure collisional broadenings in the pure rotational Raman spectrum of CO perturbed by H2 from lines S(0) to S(20) at 77, 180 ...
