摘要：

We examine the sufficient conditions for the applicability of the rotating wave approximation (RWA) for high-order multiphoton excitation (HOME) of a sparse many-level molecular level structure, and demonstrate the breakdown of the RWA for HOME of the entire bound spectrum of a Morse oscillator. We propose that the Magnus expansion for the time-evolution operator provides a useful, practical and powerful method to surpass the RWA. © 1979.
