Molecular Study of Indian Herbals at Microwave Region Using Time-domain Spectroscopy

Prashant S Rade, Pradnya H. Pawar

Abstract


The dielectric properties of liquids are useful to some extent to understand the liquid structure and molecular interactions therein. The study of dielectric properties of liquid materials is necessary not only to understand the liquid structure but also to provide technical data for practical uses in industry, science, medicine, and engineering. Time-domain spectroscopy (TDS), a spectroscopic
method used in physics uses brief terahertz radiation pulses to examine the characteristics of matter. The sample’s impact on the amplitude and phase of the terahertz energy can be detected using a generation and detection strategy that is sensitive to it. Instead of using the traditional Fouriertransform spectroscopy, that is only responsive to amplitude, the technology can measure in the timedomain and provide additional information. In the field of spectroscopy known as dielectric spectroscopy, data from dielectric relaxation are used to infer structural reform and molecular interactions. Nowadays, popularity of Indian herbals have become worldwide. Various human body issues are treated with Indian herbs, which are taken into consideration in the current work. In the
present work, interaction of Indian herbals, such as tulsi, neem, lemongrass, are taken with ethanol or methanol. The combination of Indian herbals with ethanol or methanol will be taken at different temperatures such as 15℃, 25℃, 35℃, and 45℃.
