Title
Quantenmechanische Untersuchungen der Photoisomerisierung von Retinal Modellchromophoren (German Edition),Used
Delivery time: 8-12 business days (International)
Product Description Die hocheffiziente Photoisomerisierung des Retinals wurde im Rahmen dieser Arbeit mit quantenmechanischen Methoden untersucht. Angefangen vom kleinen, minimalen Modell bis zum kompletten Retinal eingebettet im Protein wurden Molekldynamiksimulationen durchgefhrt. In allen Rechnungen wurde die Multikonfigurationsmethode CASSCF verwendet und fr ein paar ausgewhlte Modelle die strungstheoretische Korrektur zweiter Ordnung mit CASPT2 berechnet. Mit Hilfe dieser Simulationen konnte der Einfluss der Subsitution, der Modellgre und der Umgebung aufgeschlsselt werden. Die Untersuchung hat neue Erkenntnisse sowohl zur ultraschnellen Isomerisierung als auch zum raumsparenden Mechanismus hervorgebracht. About the Author Igor Schapiro hat sich nach dem Bachelorstudium in Chemie im Fachgebiet der Theoretischen Chemie spezialisiert. Nach der Zulassung zur Promotion an der Universitt DuisburgEssen 2005 setzte er sich in der Dissertation mit dem Primrereignis des Sehvorgangs auseinander. Im Rahmen der Arbeit wurde ein Programm fr Molekldynamiksimulationen implementiert und damit Berechnungen sowohl an isolierten als auch an in Protein eingebetteten Modellchromophoren durchgefhrt. Die Ergebnisse der Simulationen fhrten zum besseren Verstndnis des Reaktionsmechanismus des lichtaktivierten Prozesses. Mit der Disputation Ende 2010 wurde die Arbeit erfolgreich verteidigt.
