We present a study of liquid water and heavy water in the terahertz range at temperatures between 283K and 348K. We will fit our data with the fit@TDS software that provides a criterion to discriminate good models from others. We will present a comparison between the models proposed in the literature for liquid water and use this criterion to find the most accurate one.
