The experimental data of ultrasonic velocity, density, shear viscosity and refractive index for dimethyl substituted pyridines are reanalysed using new methodology to determine the molecular properties. The present work may be hitful for understanding the structure and interactions for the 2,4; 2,6; 3,4; and 3,s dimethyl substituted pyridines as it is directly based on the observed data and relations obtained are different !?om the existing relations.
Resonance width, shift in resonance frequency, relaxation time and activation energy of 5CB nematic liquid crystal are measured using microwave cavity technique under the influence of an external magnetic field at 9 GHz and at different temperatures. The dielectric response in liquid crystal at different temperatures and the effects of applied magnetic field on transition temperatures are studied in the present work. The technique needs a small quantity (< 0.001 cm 3 ) of the sample and provides fruitful information about the macroscopic structure of the liquid crystal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
