Medina Domínguez, Alejandro Roco, J. M. M. Calvo Hernández, Antonio Velasco Maíllo, Santiago 2004 Esprectro de vibración-rotación de haluros hidrogenados : absorción Q-brach Near-infrared spectra of HCl highly diluted in liquid Ar show intense absorption in the P-R interbranch region, so-called Q-branch absorption. In spite of its relevance for the shape of the bands, its physical origin has been elusive to date. We employ molecular dynamics simulations to study the influence of some physical effects that could contribute toQ-branch absorption. We check that multipole-induced dipole induction mechanisms are not quantitatively relevant in this spectral region. We show that the particular characteristics of accurate HCl Ar anisotropic potentials and the peculiar hindered rotational motion they provoke on the diatomic probe are essential to understand Q-branch absorption. application/pdf http://hdl.handle.net/10366/19223 http://hdl.handle.net/10366/19223 eng Blackwell's (Oxford, Gran Bretaña) Vibration rotation spectra of hydrogen halidesin rare-gas liquids: Q-branch absorption info:eu-repo/semantics/article 6 p.
