The spectrum of AsH_2(Ã ~2A_1-X ~2B_1) from 402 nm to 650 nm was first ob- served via ArF laser photolysis of AsH_3. Seven band series were assigned and the relation v=19928+868v′2-3v′2~2- (987v″_2-6v″_2~2) was obtained. The radiative lifetime of (130±20)ns was measured for AsH_2(Ã ~2A_1). Emission spectra from nascent As atom and a multiphoton ionization signal were obtained.
