Xr. Chen et al., CALCULATIONS OF STRETCHING VIBRATIONAL OVERTONES AND COMBINATIONS OF ARSINE BY NONLINEAR MODEL, Acta physica Sinica, 7(5), 1998, pp. 327-332
A three-parameter nonlinear model in nonlinear quantum theory, i.e., t
he quantized discrete self-trapping equation, has been used to calcula
te the vibrational energy spectrum, including the overtones and combin
ations with many excited quanta, of AsH stretches of arsine, AsH3. The
model calculations agree well with experiment and other calculations.
It is shown that the dominant feature of the energy spectrum of AsH3
molecule is a pattern of local mode pairs, and that when n greater tha
n or equal to 4, all the vibrational energies are almost localized on
a single AsH bond.
