## Abstract The absorption and reflection spectra of βgreenβ and βorangeβ CuGaS~2~ crystals, prepared by chemical transport reaction, have been studied at low temperatures. The βorangeβ crystal presents an excitonic spectrum characteristic for intrinsic material. The triplet structure can be explai
