The crystal structure and Raman spectrum of the sodium salt of 5-Acetic acid hydantoin

Ildiz G, Paixão JA, Castiglioni C, Fausto R. Polymorphism in 1-methylhydantoin: investigation by periodic DFT calculations and characterization of the third polymorph

In previous studies, two different polymorphs of 1-methylhydantoin were identified (forms I and II) and characterized using infrared and Raman spectroscopies, and X-ray diffraction. In this work, a new polymorph of the compound (III) is described.
