Polarized IR and Raman spectra of kdy(moo4)2 single crystals, and the 92MO-100MO isotope effect

2,4,6-trinitrophenol (TNP): An organic material for nonlinear optical (NLO) applications

“…The rotational modes are expected to have higher frequency and intensity than translational modes in the Raman spectra. The translational modes are more intense in IR spectra [20,21]. Theoretically, 21 modes are expected in Raman at low-frequency range corresponding to external modes of TNP.…”

Growth and characterization of α and γ-glycine single crystals

“…The rotational modes are expected to have higher frequency and intensity than those of translational modes in the Raman spectra. However, the translational modes are more intense in IR spectra [25,26]. a-glycine is found to have 21 external modes and those vibrations can be achieved experimentally by polarized Raman measurements.…”

Growth and characterization of 2-Methylimidazolium d-tartrate single crystal

“…The rotational modes are expected to have higher frequency and intensity than the translational modes in the Raman spectra. However, the translational modes are more intense in IR spectra [12,13] of 2MImdT. It is found to have (A +2B) translational and (A +2B) rotational vibrations in the title compound, which can be achieved experimentally by polarized Raman measurements.…”
