description This work deals with the comparison of the theoretical assignment of the DADP vibrational spectrum with the experimental displacements by isotopic labeling. For this, the DADP-C4 and DADP-C2 isotopomers were synthesized from acetone labeled isotopically in the methyl and the carbonyl carbon atoms, respectively. The acetone and DADP-isotopomer compounds were characterized using Raman and infrared spectroscopy. Theoretical assignments were taken from previous studies on the potential energy distribution of a vibrational mode, which provide an approach to the internal coordinates related to each band. The selective isotopic labeling allowed us to approach to the dependence of each band, because the energy of a molecular vibration also depends on the reciprocal mass of the atoms involved. In general, the results showed that some bands assigned experimentally do not coincide with the theoretical assignments by quantum mechanical simulations.

Para ello, se sintetizaron los isotopómeros DADP-C4 y DADP-C2, los cuales son isotopómeros parcialmente marcados. DADP-C4 y DADP-C2 fueron sintetizados a partir de acetona marcada isotópicamente en los átomos de carbonos del grupo metilo y carbonilo, respectivamente. La acetona y los compuestos isotopómeros de DADP fueron caracterizados usando espectroscopia Raman e Infrarroja. Las asignaciones teóricas fueron tomadas de estudios previos sobre la distribución de energía potencial de un modo vibracional, el cual proporciona una aproximación a las coordenadas internas relacionadas con cada banda vibracional. La marcación isotópica selectiva nos permitió acercarnos a la dependencia de cada banda, debido a que, la energía de una vibración molecular depende también de la masa recíproca de los átomos involucrados. En general, los resultados mostraron que algunas bandas asignadas experimentalmente no coinciden con las asignaciones teóricas mediante simulaciones mecánicas cuánticas.application/pdfspaUniversidad Nacional de Colombia - Sede Medellín - Facultad de Minashttps://revistas.unal.edu.co/index.php/dyna/article/view/60221Universidad Nacional de Colombia Revistas electrónicas UN DynaDynaEspinosa-Fuentes, Eduardo Antonio and Meza-Fuentes, Edgardo and Colpas-Castillo, Fredy and Castro-Suarez, John R. and Chiquillo-Correa, Gilberto and Mora, Malka (2018) Verification of the vibrational theoretical assignment of the DADP using isotopic labelling.
