AB  - Buffer-gas influence on the multiphoton absorption and dissociation in different mixtures was investigated using the simple method based on the empirical and theoretical vibrational energy distribution, generalized coupled two-level model and photoacoustic cell especially designed for low pressures studies. Energy transfer efficiency was analyzed by means of pulsed photoacoustic spectroscopy technique. Collisional effects of buffer-gas (Ar) pressure are introduced to enhance the absorption and relaxation characteristics of irradiated absorbing molecules (SF6). Functional behavior of mean number of absorbed photons per molecule (n)(total) and a dependence on buffergas pressure (P-buff) which enables us to confirm or predict some physical and chemical processes are presented. Limitation of proposed model was analyzed depending on both gas pressure and laser fluence. Results are compared with other previously obtained by the same experimental technique but for different absorber and different molecular buffer-gas. (c) 2007 Elsevier B.V. All rights reserved.
