Popis:	The long-wave band with a maximum above 300 nm in the UV spectra of substituted 5,10-dihydrophenarsazines is interpreted as a transition with intramolecular charge transfer in which the trivalent arsenic atom acts as an electron acceptor. The unshared pair of electrons of As(III) apparently makes its own contribution to the π→π transitions at 240–280 nm.
