Vibrational analysis of crystalline diketopiperazine--II. Normal mode calculations
(Elsevier, 1984)
Based on our Raman and i.r. [1] data and assignments for DKP and five of its isotopic derivatives, we have refined an intramolecular force field in a non-redundant basis. This analysis shows that the cis peptide group may ...
Histological localization of binding sites of [alpha]-bungarotoxin and of antibodies specific to acetylcholine receptor in goldfish optic nerve and tectum
(Elsevier, 1980-07-21)
Goldfish optic nerve as well as ganglion cell neurites grown in culture selectively bind rhodamine-labeled [alpha]-bungarotoxin following tissue fixation. Binding is competed for by unlabeled bungarotoxin, by carbamylcholine ...
The structure of crystalline and membrane-bound gramicidin A by vibrational analysis
(Elsevier, 1984-12-28)
The results of normal mode calculations on the [beta]4.4, [beta]6.3, [up arrow, down arrow][beta]5.6, and [up arrow, down arrow]][beta]7.2 structures of gramicidin A are compared with infrared and Raman spectra of crystalline ...
Vibrational analysis of 2,2,3-trichlorobutane and a force field for 2,2-dichloropropane
(Elsevier, 1990)
The infrared and Raman spectra of 2,2,3-dichlorobutane have been analysed in terms of normal modes calculated from a force field for secondary dichlorides refined using this molecule as well as 2,2-dichlorobutane and ...
Observation of coupled quasi-two-dimensional electronic excitations in tilted magnetic fields
(Elsevier, 1988)
We report on a magneto-Raman scattering investigation of free and donor-bound electrons in GaAs/AlxGa1-xAs quantum wells. For fields perpendicular to the layers, the spectra show intersubband transitions of photoexcited ...
Lateral mobility of tetramethylrhodamine (TMR) labelled G protein [alpha] and [beta][gamma] subunits in NG 108-15 cells
(Elsevier, 1994-08)
Multi-step signal transducing events, such as those mediated by G proteins, have been difficult to study in intact cells. We fluorescently labelled G protein subunits, tetramethylrhodamine-[alpha]O (TMR-[alpha]O) and ...
Vibrational analysis of 2,3,4-trichloropentanes
(Elsevier, 1990)
One meso form and the racemic isomer of 2,3,4-trichloropentane have been synthesized, and their infrared and Raman spectra analysed on the basis of a general force field refined for multiply-chlorinated hydrocarbons. ...
