Unformatted text preview: k for ± ± 2 k 3 Δ k ± ± < 1 < ± ± 2 k Δ k ± ± 1 2Δ k for ± ± 2 k Δ k ± ± < 1 where k is the wavevector magnitude ( k = 2 π/λ = 2 π v ), and Δ k is the wavevector bandwidth. This spectrum is shown below. For this spectrum, calculate, showing all work, the interferogram, I ( δ ), produced by the FTIR for this spectrum, where δ is the optical path diﬀerence between the two arms of the Michelson interferometer. Simplify your answer for I ( δ ) as much as possible. Put your ±nal answer in the space provided. I ( δ ) = . Prepare an accurate (computerbased) plot of the resulting interferogram. The x axis of your plot should cover from Δ k δ/π =8 to Δ k δ/π = +8. The y axis of your plot should cover from. 02 to 0 . 16....
