Research Interests

Physical Organic Chemistry

Matrix Much of the research in this area involves the preparation of molecular probes as tools for the detailed study of reaction mechanisms. This work frequently relies on the detection and study of highly reactive intermediates (e.g. radicals, carbenes and nitrenes) that are found in many chemical and some biochemical reactions. The synthesis of molecules possessing unusual physical and chemical properties by virtue of their unusual three-dimensional architectures is also an important area of investigation.

Research Topics

  • Physical organic chemistry
  • Time-resolved spectroscopy of reactive intermediates and excited states
  • Matrix isolation spectroscopy
  • Computational studies of reactive and unusual molecules
  • Synthesis of unusual molecules
