The experimental technics of Extended X-ray Absorption Fine Structure (EXAFS) is presented and several uses of it in atomic, molecular and bio physics are shown. The recent progresses of this technics, both theoretical and experimental, are discussed and ...
The vibrational overtone spectra of gaseous pyridine, 2,6-difluoropyridine, and pyrazole have been recorded using photoacoustic absorption spectroscopy. The pyridine overtone spectrum shows a progression of two peaks at each vibrational level. The widths ...
The purpose of the first part of this project is to develop a method to diagnose mammary gland hyperplasias in an animal model in vivo using optical spectroscopy, so that the progression of benign lesions could be studied over time. The absorption and sca...
Research has progressed in six principal subject areas of interest to DOE advanced (laser) isotope separation efforts. These are (1) Infrared double resonance spectroscopy of molecules excited by multiple infrared photon absorption, particularly SF sub 6 ...

The IRAS (Infrared Reflection Absorption Spectroscopy) method has been applied to the study of CO adsorption on Ni(111). Evidence has been found for the coexistence of two-fold and three-fold coordinated CO species at low CO coverages. A continuous covera...
A program to investigate the x-ray absorption behavior of materials subjected to high pressures has been continued. Of particular interest has been the EXAFS (extended x-ray absorption fine structure) and XANES (x-ray absorption near edge structure). Mate...
Molecular ions produced in an ac glow discharge cell will be probed with a single frequency tunable dye laser. The electronic-vibration-rotation spectra can be obtained by exploiting the small, but detectable, Doppler shift ( delta V/V approx.10 sup -6 )....
In the belief that further progress in understanding the dynamical behavior following photoexcitation of gas phase molecules can be stimulated by the availability of improved time-resolved spectrographic apparatus (i.e. shorter, more intense, UV excitatio...
Density of states changes in the valence and conduction band of silicon nanoclusters were monitored using soft x-ray emission and absorption spectroscopy as a function of cluster size. A progressive increase in the valence band edge toward lower energy is...
