DOI: 10.1177/00037028221120826
Abstract: Terahertz (THz) absorption spectra of the two crystalline forms of 5,5-diethylbarbituric acid (barbital) were measured with THz time-domain spectroscopy (THz-TDS). The spectra exhibited the dissimilarity between the two forms. Identification of the polymorphs and quantitative… read more here.
