The final program for the 2008 Gordon Research Conference on Electron Donor-Acceptor Interactions is given below. The conference presents and advances the current frontiers in experimental and theoretical studies of Electron Transfer and Transport in Molecular and Nano-scale Systems. The program includes sessions on coupled electron transfers, molecular solar energy conversion, biological and biomimetic systems, spin effects, ultrafast reactions and technical frontiers as well as electron transport in single molecules and devices. Over 100 poster presentations are scheduled. Four oral presentations will be selected from the posters by a committee of meeting chairs, vice-chairs and past chairs. If you want to have your poster considered for oral presentation please inform any of the vice chairs before the meeting.
