Scientists have determined the proportions of the chemical elements present in the Sun using spectroscopy.
His work in spectroscopy led to an understanding of the origin of the remarkable colours of gem stones.
Harrison's own research was in spectroscopy - the identification and analysis of chemical substances through their spectral lines.
Wei's research lies at the interface of optical spectroscopy, chemical biology, and life sciences.
Impulsive Raman spectroscopy reveals how atoms are pushed into action by light absorption.
Due to its short characteristic timescale, in the order of 10x13 s, vibrational spectroscopy provides a snapshot of the sample conformer population.
Counts were accumulated by scintillation spectroscopy for duplicate aliquots from each of the triplicate experimental samples.
Reduced cortical gamma-aminobutyric acid levels in depressed patients determined by proton magnetic resonance spectroscopy.
The methodology and limitations of gamma-ray spectroscopy are also examined for this case.
