Research Overview

Physical Organic Chemistry, Photochemistry

I am interested in the chemistry of short-lived, high energy, reactive molecules such as radicals, biradicals, carbenes, nitrenes and reactive oxygen species. Our laboratory is actively involved in the synthesis of new precursors to reactive intermediates and we study their photochemistry with the classical methods of organic chemistry (synthesis, analysis of reaction mixtures, product isolation, and the spectroscopic identification of stable reaction products). To directly observe these fascinating molecules we employ laser flash photolysis techniques with femto, pico and nanosecond time resolution, nanosecond IR spectroscopy, matrix isolation spectroscopy and computational chemistry. Our goals are both practical and theoretical. We study elementary rearrangement reactions of fundamental interest to test dynamical theories, to discover quantum mechanical tunneling processes, to understand the interactions of reactive intermediates with solvents, and to discover the molecular mechanism of action of anti-cancer drugs.

We also seek to understand how excited state molecules decompose to form reactive intermediates such as carbenes and nitrenes. To this end we use ultra fast spectroscopic methods to directly detect the excited states of azides and diazo compopunds and watch them decompose to form nitrenes and carbenes respectively. We seek to learn how the structure of the electronic state of the precursor controls its decomposition and its rearrangement to stable reaction products.
