There are only a few small inorganic molecules of fundamental importance for which thecrystal structures are unknown. Carbonic acid (H2CO3) is one of them. Raman and IR spectra of the two known polymorphs of carbonic acid are reported here. Based on the data, local structural hydrogen-bonding motifs are presentedand suggested as building blocks of the crystal structures of α-H2CO3 and β-H2CO3.
