Synchrotron infrared photoacoustic spectroscopy
The use of synchrotron radiation ~SR! as a farand mid-infrared source in the measurement of photoacoustic Fourier transform infrared spectra of solids is demonstrated for the first time in this work. Initial experiments were performed at beamline U10A at the National Synchrotron Light Source, Brookhaven National Laboratory. For synchrotron photoacoustic spectroscopy to be feasible, it must yiel...
متن کاملSubnanosecond, time-resolved, broadband infrared spectroscopy using synchrotron radiation
A facility for subnanosecond time-resolved ~pump-probe! infrared spectroscopy has been developed at the National Synchrotron Light Source of Brookhaven National Laboratory. A mode-locked Ti:sapphire laser produces 2 ps duration, tunable near-infrared pump pulses synchronized to probe pulses from a synchrotron storage ring. The facility is unique on account of the broadband infrared from the syn...
متن کاملSynchrotron Radiation Infrared and Raman Spectroscopy for Biomedical Applications
Over the last few decades, infrared (IR) spectroscopy has been recognized as a useful tool to obtain quantitative and qualitative information on IR active materials and bio-materials, with particular emphasis to polymer chemistry and organic chemistry. Nowadays, thanks to technological evolution, the possibilities offered by vibrational spectroscopy (e.g. IR and Raman spectroscopy) are much bro...
متن کاملbrain near-infrared spectroscopy (nirs)
near-infrared spectroscopy (nirs) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. typical applications include medical and physiological diagnostics. nirs can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., ...
متن کاملInfrared Science with Synchrotron Radiation
Synchrotron radiation is best known as a source of X-rays, but it is also a source for VUV to soft-Xrays photons. However, it was realised in the early 90’s that this source can also be exploited in the infrared energy domain. Even if in some frequency regions (roughly 30 microns and below) the total photon flux emitted by the synchrotron source remains inferior to that of a thermal source, the...
