摘要:

AbstractImproved room temperature Raman spectra obtained from oriented single crystals of K2SeO4of high quality are reported and discussed. The new results show that some of the earlier spectra contained spurious bands and that some genuine bands were incorrectly assigned.

摘要:

AbstractRelative intensities of the S(J) and O(J) branch lines in the fundamental and overtone bands of the vibration‐rotation Raman spectrum of a linear molecule are shown to be capable of yielding the magnitude and sign of the first and second derivatives of the polarizability anisotropy, (α∥−α⊥)′eand (α∥−α⊥)″ein relation to the equilibrium anisotropy (α∥−α⊥)e. The theory is app

摘要:

AbstractThe Raman spectra of hexamethyl benzene and HMB‐d18have been recorded as a function of temperature between 4 K and 400 K and as a function of pressure up to 8kbar. In the low‐frequency region, librational and torsional modes have been distinguished. The spectra indicate a phase transition to a high‐pressure phase IV. The polarized infrared spectra of single crystals have also been observed at different tempera

摘要:

AbstractThe polarized infrared transmission (2500–300 cm−1) and polarized Raman (2500–10 cm−1) spectra of a single crystal of monoclinic KD2PO4have been obtained. The spectra are discussed in relation to the crystal structure and properties of the hydroge
