On the use of variational wavefunctions in calculating vibrational band intensities
It is shown that vibrational band intensities calculated using variational wavefunctions and dipole surfaces give results which depend on how the Cartesian axes of the dipole surface are defined. It is suggested that the most consistent definition of these axes uses the rules proposed by Eckart for separating rovibrational motion. The consequences of this choice of axis system for the calculate...
متن کاملInfrared spectrum of solid isocyanic acid (HNCO): vibrational assignments and integrated band intensities.
Infrared spectra of thin films of solid HNCO condensed from the gas phase are characterized in terms of their vibrational frequencies, mode assignments, and integrated band intensities at low temperatures ( approximately 20-145 K). Isocyanic acid is shown to react with water (H2O) and ammonia (NH3) even at low temperatures; consequently, it may be an important species in the chemistry of inters...
متن کاملLocal Vibrational Mode Spectroscopy of Hydrogen in Compound Semiconductors
Infrared (IR) and Raman spectroscopy are useful techniques for characterizing hydrogen-related defects in semiconductors. This paper will focus on hydrogen in compound semiconductors such as AlSb, GaAs, GaN, InP, and ZnO. In most compound semiconductors studied to date, hydrogen forms neutral complexes with donors or acceptors. In GaN:Mg grown by metalorganic chemical vapor deposition, for exam...
متن کاملValence - Band Photoemission Intensities in Thorium Dioxide
Resonant photoemission spectra of the O 2p-derived valence band of insulating ThO2 are compared to linear muffin-tin orbital (LMTO) density-of-state (DOS) and XPS intensity calculations. At Th 5d corelevel threshold energies (85 ~< hv <<. 120eV), resonance is greatest at the bottom of the O 2p band where calculated p/d hybrid states are greatest; p / f hybrid content is weak by comparison. We c...
