The high resolution Fourier transform spectrum of arsine (AsH3) has be
en recorded in the region 3989-4274 cm(-1) at a resolution of 0.008 cm
(-1). About 1000 transitions are assigned to transitions of 2v(1) (A(1
)) and v(1) + v(3) (E) vibrational bands. The vibration-rotation param
eters of this overtone are obtained and discussed in the local mode mo
