This volume of Advances in Chemical Physics is dedicated, by the contributors, to Moshe Shapiro, formerly Canada Research Chair in Quantum Control in the Department of Chemistry at the University of British Columbia and Jacques Mimran Professor of Chemical Physics at the Weizmann Institute, who passed away on December 3, 2013. It focuses primarily on the interaction of light with molecules, one of Moshe''s longstanding scientific loves. However, the wide range of topics covered in this volume constitutes but a small part of Moshe''s vast range of scientific interests, which are well documented in over 300 research publications and two books.
