Abstract:
We introduce a simple three-parameter model in nonlinear quantum theory-the discrete self-trapping equation to describe the stretching spectrum of ammonia at highlying vibrational states. The model calculations appear to describe the data well. These results obtained are conducive to researching the quantum chaotic manner and the multiphoton processes and isotope separation by multiphoton dissociation of ammonia molecular system.
