The optical absorption spectrum from 0.1 to 1.5 eV photon energy is presented for extremely lightly oxygen doped crystals of La 2 CuO 4 . Crystals grown by two different methods have different low temperature spectra and different temperature depende

The weakly electric-dipole-allowed midinfrared excitations are studied in insulating single crystals of ${\mathrm{La}}_{2}{\mathrm{CuO}}_{4},$ ${\mathrm{Sr}}_{2}{\mathrm{CuO}}_{2}{\mathrm{Cl}}_{2},$ and ${\mathrm{Nd}}_{2}{\mathrm{CuO}}_{4}.$ These in

Sr{sub 2}Cu{sub 3}O{sub 4}Cl{sub 2} is a variant of the lamellar copper oxides, containing an extra Cu{sup 2+} ion in the center of every second plaquette of the square CuO{sub 2} lattice. The two types of Cu form interpenetrating Heisenberg antiferr

Measurements are reported of the transmission of single crystals of ${\mathrm{La}}_{2}$${\mathrm{NiO}}_{4}$ containing no excess oxygen. Several weak absorption bands are observed in the range 0.15--2 eV arising from magnetic and crystal-field excita
