A study of suggested formula (ADJ) of Specific Refraction book is an attempt to fulfill the pressing demand of graduate and postgraduate students of colleges as well as universities for physical chemistry research on the basis of scientific knowledge.A number of formula is investigated by the various scientists all over the world.It is worthwhile to suggest one more Empirical Formula to determine the Specific Refraction of the organic compounds. Author has try to write this book in a lucid and systematic manner.I hope this work will be helpful to the young researchers.
