In this paper the basic SF6 molecule physical characteristics are given concerning its influence on global warming and green house effect. Absorption and relaxation characteristics of this molecule have been investigated within the frame of nonlinear molecule – strong laser field interaction in different gas mixtures. All experiments have been performed on a different gas mixture pressures to analyze and investigate relaxation and energy transfer characteristics of absorbing molecules and non-absorbing collision partners. To show the SF6 absorption and relaxation and energy transfer capability comparison between SF6 and C2H4 was given using the same experimental conditions and argon as a buffer gas. All measurement points and their calculated values presented in this paper have been obtained using the infrared-pulsed photoacoustics technique adopted for atmospheric and subatmospheric pressures
