Description / Table of Contents:
Raman and infrared spectra of ethylmalonic acid [C2H5CH(COOH)2, C2H5CD(COOD)2] and its potassium salts [C2H5CH(COOH)(COOK), C2H5CD(COOD)(COOK) and C2H5CH(COOK)2, C2H5CD(COOK)2] in aqueous solution were recorded from 3500 to 200 cm-1. The analysis of the polarization of the Raman lines led us to the conclusion that ethylmalonic acid and its dipotassium salt belong to Cs and the acid salt to the C1 group. An assignment of the observed lines as fundamentals is proposed.
Notes:
Les spectres Raman et infrarouge de l'acide éthylmalonique [C2H5CH(COOH)2, C2H5CD(COOD)2] et de ses sels alcalins [C2H5CH(COOH)(COOK), C2H5CD(COOD)(COOK) et C2H5CH(COOK)2, C2H5CD(COOK)2] en solution aqueuse ont été enregistrés de 3500 à 200 cm-1. L'analyse du facteur de dépolarisation nous a permis de conclure que l'acide et le dianion appartiennent au groupe de symétrie Cs le sel acide appartenant au groupe C1. Une attribution des vibrations fondamentales est proposée.
