The vibrational features of carbon monoxide (CO) adsorbed on Ir(111) were studied by means of high-resolution core-level spectroscopy. By monitoring the Ir 4f 7/2 core level as a function of exposure, we proved that the CO adsorbs on the surface always in on-top sites, in agreement with the results of vibrational spectroscopy techniques and density functional theory studies. The C 1s vibrational splittings measured for the p(√3 × √3)R30°(233.4 ± 0.5 meV) and c(4 × 2√3)rect (231.4 ± 0.4 meV) structures were in good agreement with the Z + 1 model. Despite the very small error bar of the measurements, it was not possibile to reveal any anharmonic contribution to the spectral lineshape. We speculate that the contribution of the unresolved vibrational mode of the frustrated translation or the effect of phonon-mediated interaction with the substrate can account for the observation of this outcome.

This article develops an alternative perspective on the Argentine military, addressing their narratives of everyday life in the 1970s and during the last dictatorship (1976–1983). By approaching the military as a community of families, it analyses how former officers of the regime, their wives and their children recount the years of political violence. Due to its ethnographic bottom‐up approach, the article challenges the traditional focus on the monolithic masculine narratives of the military in Latin America. Instead, it presents an innovative interpretative framework in which different understandings of violence and political confrontation emerge, showing a plurality of under‐researched elements that compose military identities in Argentina.
