High-Resolution Spectroscopic Study of Arsine - 3V(1) and 2V(1)+v(3) Dyad - The Tendency of Symmetry Reduction
The high resolution spectrum of AsH3 3 nu(1) and 2 nu(1)+nu(3) stretching overtone dyad was recorded and analyzed. The major vibration-rotation parameters of these overtones were obtained. The result indicates that these overtone vibrational states are close to the local mode limit and the rotational levels show the tendency to approach an asymmetric top,
