International Conference on Electronic Spectroscopy and Structure (ICESS) is a series of conferences that brings together world leading experts on electronic structure and spectroscopy. The conference series dates back to 1971, when the International Conference on Electronic Spectroscopy (ICES) was held in Asilomar, USA. Since then the conference has started to attract a wider community with more than 300 scientists from 21 countries participating in ICESS-14 held in 2018 in Shanghai, China. The scientific program of ICESS-14 consisted of altogether 8 plenary lectures, 40 invited talks as well as 41 oral presentations and 120 poster contributions.

Following the proud tradition of the ICES and ICESS series, University of Oulu is glad to host the 50th Anniversary of the conferences series, 15th International Conference on Electronic Spectroscopy and Structure in its northernmost location yet: in Oulu, Finland (August 23rd to 27th, 2021). 

ICESS-15 will cover topics related to atomic and molecular sciences, photochemistry, quantum materials, imaging spectroscopies, novel instrumentation and nanomaterials. Special focus of the conference is in highlighting the new developments and applications of the use of synchrotron radiation and free electron lasers around the globe. We provide a full five-day program of plenary presentations and parallel and poster sessions with the most cutting-edge developments and science in these, as well as a chance to experience the beautiful arctic summer and Finnish nature at the same time.

In addition, a special session will be held in the memory of Prof. Charles Fadley, and his accomplishments and contributions to the fields of x-ray photoelectron spectroscopy and photoelectron diffraction.

We invite the world leading knowledge on electronic structure and applied fields to take the challenge and build together a world-leading conference on spectroscopy and structure!
