By Shri Singh
For graduate scholars and researchers in condensed subject physics, chemical physics, fabrics technological know-how, and engineering, Singh (Banaras Hindu U.) stories the literature reporting advancements over the last 3 a long time about the nature of liquid crystals and their software to varied reasons. He in general assumes readers to be new to the fabrics, yet does delve deeply right into a few issues for readers with massive historical past in them. After discussing the most varieties and type, distribution capabilities and order parameters, and actual houses; he surveys a few of the kinds; and concludes via interpreting defects and textures.

The interaction of the spins with the static magnetic field is called the Zeeman interaction. The exchange and dipolar interactions arise due to the interactions between different spins. In addition, typical interactions of the nuclear quadrupole charge distribution with the electric field gradient may arise. The relevant interactions involved in the nmr and ESR experiments are as follows11: (i) Zeeman interactions (a) electronic ^iB B • g • s , (b) nuclear - \nN B • o - 1 , where fiN and \iB are, respectively, the nuclear and Bohr magnetons, g and o are called the g-tensor and chemical shielding tensor, respectively, B is the magnetic flux desity, s is the electron spin operator and I is the nuclear spin operator.
