Brain MRI with laser-polarized 129 xe
(Wiley Subscription Services, Inc., A Wiley Company, 1997-11)
The feasibility of brain MRI with laser-polarized 129 Xe in a small animal model is demonstrated. Naturally abundant 129 Xe is polarized and introduced into the lungs of Sprague-Dawley rats. Polarized xenon gas dissolves ...
Vibrational spectra in the C---H stretching region and the structure of the polymethylene chain
(Elsevier, 1978)
The C---H stretching regions of both the Raman and i.r. spectra of the extended polymethylene chain have broad secondary maxima. In the case of the Raman spectrum, line shapes are dependent on the environment of the chain, ...
