英文摘要: A computing model is presented for the calculation of the transient population distribution of polyatomic molecules excited by an IR laser pulse, SF8 has been used as an example. This model allows the calculation of the vibrational energy distribution from the observe IR fluorescence or adsorption spectrum, and vice versa. The thermal vibrational distribution calculated by this model the measured spectrum of SF6 at 300 K is in good agreement with the Boltzmann distribution (Table 1). The present model has a few advantages over an earlier study((1)), such as higher precision of computation, accurate generation of the vibrational transition matrix and being capable of calculating the transient vibrational population distribution at any instant after laser excitation. Using the model as rotationally resolved spectrum of SF6 at 20K has been obtained for the first time.
