The contributors deliver a practical and up-to-date exploration of the characterization and applications of CTCs. The book covers the Spectroscopic Characterization methods for obtaining accurate information on electronic structures of CTCs. The book consists of 5 chapters: Chapter I deals with the introduction of CTC spectroscopic techniques and bioassay. Chapter II deals with Catalytic activity and DNA binding applications of charge transfer complex formed between Benzhydrylpiperazine and p-Chloranil: Synthesis, spectroscopic, and DFT studies. Chapter III deals with Hydrogen Bonded Charge...
