The design of writing this book entitled "Single Crystal X-Ray Study of 1,4-Dihydropyridines" is a outcome of an analysis of Organic scaffolds by Single Crystal X-Ray techniques. Our plan of this section of the book is not to discuss the scope of X-Rays, but we want to make the students familiar with the X-ray diffraction crystallography for organic molecules. Text book covered by the Characterization and dipped study of Single Crystal X-Ray studies of Single Crystal X-Ray Study of 1,4-Dihydropyridines.
