Título: | Coherence effects between intramolecular vibrational relaxation and dissociation in triatomic van der Waals systems |
Autor: | Roncero, Octavio CSIC ORCID ; Villarreal, Pablo CSIC ORCID; Delgado Barrio, Gerardo CSIC ORCID ; Halberstadt, Nadine; Janda, Kenneth C. | Fecha de publicación: | 1993 | Editor: | American Institute of Physics | Citación: | Journal of Chemical Physics 99: 1035- 1049 (1993) | Resumen: | Time-independent [Halberstadt and co-workers, J. Chem. Phys. 96, 2404 (1992); 97, 341 (1992)] and time-dependent quantum mechanical calculations that describe the intramolecular vibrational relaxation (IVR) of Ar⋯Cl 2 are used to develop analytical models for this process. It is shown that time-resolved experiments should reveal an oscillatory dissociation rate. It is found that the oscillations will be different for different rotational levels, and may tend to wash out if insufficient state selection is achieved in the initial excitation step. This may explain why no such oscillations were observed for Ar⋯I2. It is also predicted that the observed product state rotational distribution will change with the initially excited rotational state. © 1993 American Institute of Physics. | URI: | http://hdl.handle.net/10261/71740 | DOI: | 10.1063/1.465403 | Identificadores: | doi: 10.1063/1.465403 issn: 0021-9606 |
