Raman Study

Raman spectra of oriented single crystals of KNO3(II) have been recorded at 298 and 77 K. At both temperatures the data are in excellent agreement with the factor group analysis based on the generally accepted Pmcn space group. Additional spectral features observed near room temperature suggest the presence of a significant number of disordered nitrate groups on alternate lattice sites, although the majority of nitrate groups occupy the ordered sites. As the temperature is lowered, the disordered groups freeze out until near the temperature of reported electrical anomalies (213 K) only the ordered sites are occupied. Improved resolution has resulted in detection of a number of new spectral features while improved depolarization data have resulted in reassignment of several peaks.

The use of a Fabry–Perot etalon for the study of the pure rotational Raman spectra of oxygen and nitrogen is described. By using an etalon having a plate separation of 12 mm, a resolution of 0.1 cm -1 is readily achieved. The use of a Fabry-Perot etalon allows the wavelength of the individual rotational lines to be measured with high accuracy and leads to precise values for the rotational constants of oxygen and nitrogen. The rotational constants obtained are for N 2 B 0 = 1.98950 6 ±0.00002 7 cm -1 , D 0 = (5.48±0.05 5 ) x 10 -6 cm -1 ; for O 2 B 0 = 1.437682 ±0.000009 cm -1 , D 0 = (4.85 2 ± 0.01 2 ) x 10 -6 cm -1 . The values determined for oxygen are in excellent agreement with recent microwave measurements of these constants.
