  2. 1. Carbenes: The Gathering : Photophysics of Transition Metal Carbene Complexes

    Author : Nidhi Kaul; Leif Hammarström; James K. McCusker; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photophysics; time-resolved spectroscopy; transition-metal complexes; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

    Abstract : This thesis explores the photophysics of some transition-metal complexes (TMCs) which utilize N-heterocyclic carbenes as ligands. After a historical interlude which traces the development of the broader field of transition metal complexes and their photophysical investigations, there is an overview of theoretical concepts and the spectroscopic methods employed.
