Abstract

Using 355 nm excitation laser radiation, the stimulated Raman scattering (SRS) lines of methane between 14000 and 26000 cm^-1 at different experimental conditions were recorded. Two sets of successive SRS lines manifesting the Raman shift in the ν₁ and ν₂ modes of vibration in the ¹A₁ electronic state of CH ₄ have been assigned. The evolution of SRS lines at different pressures has been investigated. The energy dependence of SRS lines has revealed that SRS line due to higher order components become stronger than the fundamental at higher laser pump energy.
