The theory of linear and non-linear optical processes in conjugated polymers is introduced. In particular, the Condon approximation, Franck-Condon factors, and exciton model are all used to develop expressions for transition dipole moments between the electronic states. The non-linear processes of two-photon absorption and electroabsorption are discussed within the context of the essentials states mechanism.The chapter concludes with a discussion of photo-physical processes via a Jablonski diagram.Less

This book presents a unique interplay of leading scholars and journalists working on the contentious topic of immigration. The chapters reflect on how hard it is to write about one of the defining issues of our time—one that is at once local and global, familiar and uncanny, concrete and abstract. Highlighting and framing central questions surrounding immigration, the book explores topics including illegal immigration, state and federal mechanisms for immigration regulation, enduring myths and fallacies regarding immigration, immigration and the economy, immigration and education, the adaptations of the second generation, and more. Together, these chapters give a clear sense of the ways in which scholars and journalists enter, shape, and sometimes transform this essential yet unfinished national conversation.Less
