Hello, my name is Cahit Örek. I am working in the groups of Prof. Niyazi Bulut in the area of theoretical/computational Physical Chemistry of small gas phase molecules. My research involves state-of-the-art electronic structure calculations of potential energy surfaces (PESs) for various atom/molecule complexes that contain radicals. My developed PESs are then used in quantum scattering calculations of relevance in molecular spectroscopy, cold-atom collisions, and astrophysical chemistry.
