Question

the original given spectra is not visible either. It is more as a guide with the pattern of the graph

7) (12 marks) Figure 1 (in the accompanying file Spectroscopy assignment-spectra and rubric) is a spectrum of the anti-symmetric stretch of the absorption bands of room temperature CO2 including the positions of the peaks. For 12C1602 this band occurs at an origin of 2349.16 cm1, (i) I clearly the P, Q (if present), and R rotational branches and dentify explain why there are differences between the intensities and line spacing of the peaks in each of the branches. ii) Explain what factors contribute to the relative intensities of the rotational lines including any symmetry restrictions. 12 00) HOO 065 Fi May 13 15 48 20 206 M 0 冲 0.0040 0.0000 0 0040 0045 .0050
