The Raman spectrum of methyl iodide was recorded in the 3000 cm −1 region with a resolution of 0.25 cm −1 . The range measured includes the ν 1 , ν 4 bands of symmetry species A 1 and E , respectively. Using published vibrational–rotational constants, a computer simulation of the band contour was carried out, yielding relative values of Raman polarizability derivatives for these bands. Further, from previous measurements of the scattering cross‐section the moduli of the Raman tensor components related to ν 1 and ν 4 vibrational modes were determined.
