Configuraciones nucleares en la entonación del español de Antioquia, Colombia

The main objective of this article is double. On the one hand, to describe nuclear configurations and, on the other hand, to analyze phonetically assertive statements with informative broad focus and absolute interrogatives, in the Spanish spoken in Apartadó and Medellín, two cities of Colombia. This research analyzes 112 sentences, uttered by 32 speakers, prestratified by sex, age and sociocultural background. Results suggest that assertive statements with broad focus and absolute interrogatives show, predominantly, the same nuclear configuration (L* L%, H+(!)L* L%) in both cities. Therefore, they could be considered as speaking communities with very similar prosody, although traditionally they belong to different dialect zones. Finally, it is necessary to work with different corpora and with phonetic analysis, as well as intonation studies of perception, that will provide information to establish if there are phonological differences between both sentence modalities.

Monitoring nonadiabatic dynamics in molecules by ultrafast X-Ray diffraction

We theoretically examine time-resolved diffraction from molecules which undergo non-adiabatic dynamics and identify contributions from inelastic scattering that indicate the presence of an avoided crossing and the corresponding nuclear configuration.

Conformer specific nonadiabatic reaction dynamics in the photodissociation of partially deuterated thioanisoles (C6H5S-CH2D and C6H5S-CHD2)

Multidimensional aspects of the conical intersection in the nuclear configuration space have been explored by partial H/D substitution of the methyl moiety of pre-dissociating thioanisole.
