Figure 7
The room temperature Raman spectrum of \(L{i}_{2}N{i}_{2}M{o}_{3}{O}_{12}\) obtained by exciting the sample with an incident laser beam of wavelength 488 nm is shown in the top panel. The bottom left and right panels show the variation of the spectral features corresponding to \({\nu }_{1}\), \({\nu }_{2}\), \({\nu }_{3}\), \({\nu }_{4}\) in the tempurature range 4.2 to 25 K and 100 to 250 K. The solid lines are guides to the eyes.
