Abstract The 4.2 K optical absorption spectra of Ia-(NdO)2CO3 and II-(NdO)2CO3 are reported. Type Ia exhibits, apparently, a single site for neodymium, and type II, at least two sites. Electron-diffraction patterns obtained from flakes suggest a large orthorhombic unit cell for type Ia and confirm the hexagonal symmetry of the unit cell of type II.
