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 ...
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. ...
A polarized photobleaching study of chromatin reorientation in intact nuclei
(Elsevier, 1990-08-20)
Polarized fluorescence recovery after photobleaching (pFRAP) was used to monitor the effects that condensation, i.e. compaction and aggregation, have on the ([mu]s and ms) internal dynamics of chromatin in intact nuclei. ...
Normal-mode analysis of infrared and Raman spectra of poly(vinyl fluoride)
(Elsevier, 1992-03-02)
Infrared and Raman spectra of samples of poly(vinyl fluoride) (PVF) have been recorded. The vibrational spectra have been analyzed by means of normal-mode calculations. A force field was derived by using 2-fluorobutane as ...
Comment on “Effects of 60 Hz electromagnetic fields on early growth in three plant species and a replication of previous results” by Mark S. Davies

No abstract.
Comprehensive force field for multiply-chlorinated hydrocarbons
(Elsevier, 1990)
A force field is presented that has been optimized for chlorinated hyrocarbons containing isolated, vicinal, and geminal secondary chlorines. For carbon--chlorine stretch modes, 74 frequencies in 10 molecules are reproduced ...
Lack of correspondence between the room-temperature phosphorescence decay-components and Trp residues in a series of Trp-->Cys or Trp-->Phemutants of human carbonic anhydrase II
(Elsevier, 1994-10-17)
The room temperature phosphorescence of native human carbonic anhydrase (CA), and several mutants of this enzyme has been investigated. In these mutants the seven tryptophan residues in the native protein have sequentially ...
Polarized Raman spectra of oriented films of Α-helical poly( L -alanine) and its N -deuterated analogue
(John Wiley & Sons, Ltd., 1998-01)
Polarized Raman spectra were obtained on well oriented films of Α-helical poly( L -alanine) (Α-PLA) and its N -deuterated analogue in order to obtain definitive assignments of the E 2 -species modes. Such assignments ...
High resolution laser spectroscopy of relaxation and the excitation lineshape of excitons in GaAs quantum well structures
(Elsevier, 1990-04-01)
A new class of measurements on GaAs quantum well structures based on frequency domain nonlinear laser spectroscopy is described. Room temperature measurements of the excitation relaxation show an interference effect in the ...
