Refractive index of methane
Web1 day ago · Silica used as the proposed methane gas sensor’s background material, and the Sellmeier equation was used to calculate the background material’s refractive index [25]: (1) n λ = 1 + ∑ i = 1 l A i λ 2 λ 2 − B i, where l = 3, A 1 = 0. 6961663, A 2 = 0. 407926, A 3 = 0. 8974794, B 1 = 0. 00467914826 μ m 2, B 2 = 0. 0135120631 μ m 2, and B 3 = 97. 9340025 … Web6.1 Essential State Model. It follows from eqn [37] that all excited states contribute to the nonlinear optical susceptibility. However, similarly as for refractive index, the absorption bands closest to the excitation wavelength and to the virtual states (cf. Figure 7) contribute the most significantly.
