The values of ultrasonic velocity is measured by using ultrasonic interferometer for 0.01M solution of entacapone in methanol, ethanol, 1-propanol and 1-butanol as a solvent at 303.15 K by using frequency 2 MHz, 4 MHz and 6 MHz. This experimental data is used to explore the acoustic properties like intermolecular free length, relative association and apparent molar compressibility. From these thermodynamic and acoustic properties, the molecular interactions like solute-solute and solute-solvent occurring in solution have been interpreted with respect to change in solvent at different frequencies. It was observed that apparent molar compressibility value decreases from 2 MHz to 6 MHz in solvent Methanol to 1-butanol. Decreasing trend in Ultrasonic velocity shows less interaction between solute and solvent molecules. From 2 MHz to 6 MHz intermolecular free length increases which shows weak molecular interaction. Relative association increases from methanol to 1-butanol from increasing frequency i.e. from 2MHz to 6MHz. It shows strong solute solvent interaction. © 2016, Association of Pharmaceutical Teachers of India. All rights reserved.

Paracetamol is an antipyretic drug, when it is taken it reduces the body temperature. So it was thought better to study intermolecular interaction and thus behavior of paracetamol under varied conditions such as temperature, concentration etc. For this certain important physical parameters such as adiabatic compressibility, specific acoustic impedance, relative association, intermolecular free length, relaxation time, free volume, Rao's constant, Wada's constant etc. are evaluated using ultrasonic velocity, density and viscosity of paracetamol solution at different concentrations and at 303K.

Research and development in the field of ultrasonics is growing steadily. Ultrasonic non-destructive testing is a resourceful technique that can be appropriate for the study of liquids, liquid mixtures and solutions. Ultrasonic studies may throw more light on the molecular interaction to know the behavior of solute and solvent molecules in liquid mixtures and solutions. Changes in concentration and temperature affect compressibility of solution, which in turn affects molecular interactions in liquid mixtures and solutions. Experimental measurement of ultrasonic velocity and density have been carried out on aqueous solution of ampicillin sodium at different concentrations, temperatures and different frequencies such as 2MHz, 4MHz and 6MHz. Ultrasonic velocity and density data have been used to calculate acoustical parameter such as adiabatic compressibility, specific acoustic impedance and intermolecular free length have been used to explain solute-solute, solvent-solvent and solute-solvent interaction and structure making and structure breaking properties of solute in aqueous solution of ampicillin sodium.

There are many techniques available to study physical properties to interpret the molecular interaction in liquids, liquid mixtures and solutions. The study of ultrasonic waves through solution is found to be quite interesting. The study of ultrasonic waves through solution is used for knowing the nature and strength of intermolecular forces and their interaction in liquids, liquid mixtures and solutions. Thermo-acoustical and its allied properties are very helpful in predicting the physico-chemical behavior and molecular interactions occurring in liquids, liquid mixtures and solutions. Hence this motivates the researchers to take up the research project in the field. Ultrasonic velocity, density and viscosity have been measured for antibiotic ampicillin sodium in water at different concentrations, temperatures and different frequencies such as 2MHz, 4MHz and 6MHz, with a view to investigate the exact nature of molecular interactions. From the experimental data, ultrasonic parameters such as relative association, specific acoustic relaxation time and free volume have been computed. The results have further been used to interpret the nature and strength of molecular interactions in the aqueous solution of ampicillin sodium.

Ultrasonic velocity measurement provides an important tool to study the liquid state. The measurement of ultrasonic velocity in liquid mixture provides valuable information about their physico-chemical properties and nature of molecular interaction in them. Ultrasonic parameters provide valuable information about various inter and intra molecular interactions in solution. Cefotaxime sodium is used as an antibiotic in pharmaceutical. It is antibacterial, β-lactum; third generation cephalosporin. Ultrasonic velocity, density and viscosity of aqueous solution of cefotaxime sodium at different concentrations, temperatures and different frequencies such as 2MHz, 4MHz and 6MHz have been experimentally determined. Ultrasonic parameters such as adiabatic compressibility, intermolecular free length and relaxation time of these solutions are computed on the basis of these measurements. Various molecular interactions in these solutions have been analyzed on the basis of the variation of these parameters with concentration, temperature and frequency.

Considering the impacts of industrial effluents on the quality of water of many dams and rivers as reported in the literature, a study of water quality of Pench Reservoir (India) has been carried out. In the present work, physico-chemical parameters and bacteriological status are evaluated to determine its suitability for drinking and irrigation. From various parameters like pH, DO, BOD,COD, EC and minerals etc, it is concluded that the water is suitable for drinking. Also contents of chlorides, TDS, SAR, Na%, and RSC are within the limits accepted for irrigation, therefore, the water can be classified as fit for irrigation purpose.

Salicylic acid is a basic nucleus used for the synthesis of different antipyretic, analgesic and antibiotic drugs which are widely used in medicinal field. Various techniques have been used to study intermolecular interactions, one such technique is the measurement of ultrasonic velocity. Ultrasonic parameters provide valuable information about various intermolecular interactions in solution. Measurements of ultrasonic velocity, density and viscosity of 0.01 M solution of salicylic acid in ethanol have been carried out at 303.15 K at different frequencies. The experimental data was used to calculate various acoustical parameters such as adiabatic compressibility (β), apparent molar compressibility (Φ k), specific acoustic impedance (Z), relative association (R A), relaxation time (τ) and intermolecular free length (L f). The results are interpreted in terms of solute - solvent interactions occurring in the solution.

Ultrasonic is a powerful nondestructive technique having wide range of applications in the field of material science. When ultrasonic wave passes through the medium these waves can actively interact with medium and activate the different processes in the medium. Structural changes occurring in the medium are explained in the form of velocity of propagation and amplitude of absorption. These two parameters are used as a function of temperature, pressure and frequency to evaluate several thermo acoustic parameters which gives detailed information about the molecular interaction. Ultrasonic velocity, density and viscosity measurements of Dichlofenac sodium in aqueous media have been made at different concentrations, temperatures and at different frequencies such as 2MHz, 4MHz and 6MHz. The data obtained during the investigation may give information regarding drug absorption, transmission and effect of the drug.
