UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe coupled cluster CC2 method has been employed for the computation of dipole moments and static first order hyperpolarizability of a large size push–pull molecule with an extended p electron system. The results are critically compared with the outcomes of electro-optical absorption measurements. CC2 ground and excited state dipole moments are slightly overestimated with respect to the experimental ones, but their differences are well reproduced; good agreement has also been found for absorption wavelengths. Sum of state computations of the static first hyperpolarizability highlight the importance of at least two excited states.

| Abstract: | The coupled cluster CC2 method has been employed for the computation of dipole moments and static first order hyperpolarizability of a large size push–pull molecule with an extended p electron system. The results are critically compared with the outcomes of electro-optical absorption measurements. CC2 ground and excited state dipole moments are slightly overestimated with respect to the experimental ones, but their differences are well reproduced; good agreement has also been found for absorption wavelengths. Sum of state computations of the static first hyperpolarizability highlight the importance of at least two excited states. |
