Pure undamaged NaClO 3 and KClO 3 crystals show four Raman lines arising from the internal oscillations in the ClO 3 ion, besides a few other Raman lines due to lattice oscillations. On radiation damage by X-rays or γ-rays some new lines are observed in each crystal.

1989年1月1日 · Raman measurements of KClO 3 from 77 to 630 K have confirmed the presence of a single phase transition at about 545 K. The transition was monitored by following the temperature dependence of the frequency and intensity of two external lattice modes of Ag character at about 50 and 80cm −1.

1991年1月1日 · Raman spectra at high pressure have been obtained for KBrO 3, NaClO 3 and NaBrO 3 in a diamond anvil cell. A phase change has been found for KBrO 3 at 19 kbar; at 24 kbar for NaBrO 3; and at 36 kbar for NaClO 3.

The Raman spectra of single crystal KClO3 were measured in the region above 30 cm−1 at 298 and 77°K. Single crystal infrared spectra in the internal mode region were measured by reflection at 298°K.…

As shown in Figure 2 a, highquality Raman spectra for 1 mg of KClO3 on an aluminum plate at distances of 3 m, 5 m, 6 m, 8 m, and 10 m are achieved. The most intense Raman peaks are clearly...

The Raman spectra of KClO 3 are reported at room temperature up to pressures of 60 kbar in a diamond-anvil cell. The phase transition between phases I and II occurs at approximately 7 kbar, is sluggish and the spectra show that the two phases coexist over a pressure range of approximately 5 kbar.

1973年11月1日 · The resonant frequencies, damping constants and oscillator strengths of far infrared lattice vibrations of polycrystalline NaClO 3, KClO 3, NaBrO 3 and KBrO 3 have been obtained through classical dispersion (CD) analysis of transmission data.
