An investigation of the SH1-SH2 and SH1-ATPase distances in myosin subfragment-1 by resonance energy transfer using nanosecond fluorimetry
(Elsevier, 1985-11-08)
The separation between the two reactive thiols SH1 (Cys-704) and SH2 (Cys-694) and that between SH1 and the active site of myosin subfragment-1 were further investigated by Forster energy transfer techniques. The SH1-SH2 ...
Excited state spectroscopy of para di-substituted benzenes in a supersonic beam using resonant two photon ionization
(Elsevier, 1986)
Excited state vibronic spectra of p-aminophenol, p-cresol, p-fluoroaniline, p-fluorophenol, hydroquinone and p-toluidine have been obtained using resonant two photon ionization supersonic beam mass spectrometry. Despite ...
Vibrational analysis of conformation in peptides, polypeptides, and proteins This is paper number 16 in a series of which Ref. 20 is paper 15.
(Wiley Subscription Services, Inc., A Wiley Company, 1983-01)
A vibrational force field for the polypeptide chain has been developed for normal-mode analysis of such molecules. It can reproduce observed frequencies of known structures to within about 5 cm −1 . We review the application ...
Effect of Crystallization of the Grain-Boundary Phase on the Thermal Diffusivity of a Sialon Ceramic
(Blackwell Publishing Ltd, 1984-05)
Intramolecular azide-diene cycloadditions. An approach to fused bicyclic 3-pyrrolines based on a one-pot nitrene-diene cycloaddition equivalent.
(Elsevier, 1986)
Cyclization of heterosubstituted [omega]-azidodienes 11 provides fused bicyclic 3-pyrrolines 12 in one operation. These pyrrolines are potentially useful intermediates for natural products synthesis, as illustrated by ...
Schottky contributions in chemical thermodynamics
(Kluwer Academic Publishers; Wiley Heyden Ltd., Chichester and Akadémiai Kiadó, Budapest ; Springer Science+Business Media, 1985-11)
Cryogenic heat-capacity determinations provide a useful tool for the determination of the energetic spectrum of condensed phases and also reveal information on their discrete electronic level structures as well. We have ...
Excitation temperature, degree of ionization of added iron species, and electron density in an exploding thin film plasma
(Elsevier, 1981)
Time and spacially resolved spectra of a cylindrically symmetric exploding thin film plasma were obtained with a rotating mirror camera and astigmatic imaging. These spectra were decouvolved to obtain relative spectral ...
Computer simulation of recrystallization in non-uniformly deformed metals
(Elsevier, 1989-02)
The classical Johnson-Mehl-Avrami-Kolmogorov (JMAK) equation [F = 1 - exp(- kt)n] for nucleation and growth transformations works very well for most solid state transformations but fails regularly when applied to ...
Electron diffraction analysis of charge redistribution model and structure of SeF6
(Elsevier, 1984-08)
The bond length of the octahedral molecule SeF6 was found to be rg(3[sigma]) = 1.685(2) A. Mean amplitudes of vibration, measured by diffraction, were within the experimental error of those calculated from spectral data ...
