Centrifugal Distortions in Linear Triatomic Molecules: Application of an ab Initio Approach to HCP
(Elsevier, 1993-12)
Our previously outlined method (J. Mol. Struct. THEOCHEM99, 265-270, 1989) for employing analytic quantum chemical gradients to calculate the geometries, energies, and quartic spectroscopic constants for centrifugally ...
High yield synthesis of high specific activity R-(-)-[11C]epinephrine for routine PET studies in humans
(Elsevier, 1993-11)
R-(-)-[11C]Epinephrine ([11C]EPI) has been synthesized from R-(-)-norepinephrine by direct methylation with [11C]methyl iodide or [11C]methyl triflate. The total synthesis time including HPLC purification was 35-40 min. ...
Vibrational analyses of 2,4-dichloropentane and 2,4,6-trichloroheptane
(Elsevier, 1974-04)
This study of the vibrational spectra of 2,4-dichloropentane and 2,4,6-trichloroheptane uses normal coordinate calculations as a probe for the presence of different molecular conformers. The calculations use a complete ...
Analysis of the low temperature fluorescence and phosphorescence spectra of p-difluorobenzene
(Elsevier, 1983-11)
The low temperature fluorescence spectra (4.2 K) of solid solutions of p-difluorobenzene-h4 (pDFB-h4) and -d4 have been recorded and analyzed. The absence of fluorescence from vibrationally excited states at 4.2 K eliminates ...
Raman spectroscopy monitoring of the cellular activities of a tissue-engineered ex vivo produced oral mucosal equivalent
(John Wiley & Sons, Ltd., 2011-02)
To ensure quality control and assurance in tissue engineering, noninvasive, real-time and aseptic evaluation of cell-based devices is required before product release. In this study, Raman spectroscopy was applied to monitor ...
The appended curve technique for deconvolutional analysis —method and validation
(Springer-Verlag, 1988-09)
Deconvolutional analysis (DCA) is useful in correction of organ time activity curves (response function) for variations in blood activity (input function). Despite enthusiastic reports of applications of DCA in renal and ...
Scintigraphic detection of sinusitis
(Springer-Verlag, 1988-11)
Radionuclide scintigraphy is useful in the diagnosis of sinusitis. Three cases are described, using different radionuclide agents ( 99m Tc-MDP, 67 Ga-citrate and 111 Inleukocytes) in which sinusitis was discovered, though ...
Vibration-rotation energies of tetrahedral XY4 molecules : Part II. The fundamental [nu]3 of CH4
(Elsevier, 1961)
The matrix elements derived in the first paper of this series are used to compute the frequencies of the tetrahedral fine structure components of the rotational lines of the fundamental [nu]3 of CH4. The theoretically ...
Vibrational studies of the disulfide group in proteins. VII. Normal mode analysis of the Raman spectra of erabutoxin, γ‐II crystallin and immunoglobulin
(John Wiley & Sons, Ltd., 1992-10)
Normal mode calculations have been made on the known structures of disulfide bridges in erabutoxin b, a form of γ‐II crystallin, and fragments (Fab, variable‐domain of Bence‐Jones proteins) of immunoglobulins. Previously ...
Focal fluorine-18 fluorodeoxyglucose accumulation in inflammatory pancreatic disease
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-03)
Focal 2-deoxy-2-[fluorine-18]fluoro- d -glucose (FDG) uptake on positron emission tomography (PET) in a pancreatic mass has been reported as a specific finding for pancreatic carcinoma. Inflammatory conditions of the ...
