In this book, some novel benzothiazole derivatives were synthesized and characterized by IR, Mass and NMR spectroscopy. This book is divided into four chapters. First is Introduction, second is Experimental, in which, synthesis of benzothiazole derivatives are included. The third chapter is on spectral data, contains FT-IR, Mass, proton and carbon NMR of synthesized benzothiazole derivatives. while fourth chapter is References. This book is useful for researchers.
