Frequency of neoplasia in systemic lupus erythematosus and rheumatoid arthritis
(John Wiley & Sons, Inc., 1976-11)
A patient population admitted to the hospital for either SLE or RA was surveyed for the subsequent development of neoplasms. The frequency of neoplasm in SLE patients appeared to be exaggerated, whereas the frequency of ...
Carbon suboxide as a quasilinear molecule with a large amplitude bending mode : Determination of the molecular constants and the [nu]7 potential function
(Elsevier, 1976-12)
The model of a quasilinear molecule with a large amplitude bending mode is used to treat C3O2. The Hamiltonian operator, including the rotation-vibration interaction, is derived allowing only a single vibrational degree ...
Normal coordinate analyses of molecules with the amide group
(Elsevier, 1971-01)
Normal coordinate analyses have been performed on molecules with the amide group using force constants transferred from N-methylacetamides and polyamides. The molecules involved were hexamethylenedipropionamide, ...
Comments on "the interpretation of the EPR and Mossbauer spectra of two-iron, one-electron iron-sulfur proteins"
(Elsevier, 1971-12-03)
Evidence is presented indicating that the note mentioned in the title is incorrect in two important aspects. 1.) According to our results of ENDOR spectroscopy and computer simulations of Mossbauer spectra, the conclusions ...
Instrumental improvements for rapid, detailed kinetic studies of oxygenase activity
(Elsevier, 1979-07-15)
The characteristics of an electronic differentiator that facilitates continuous monitoring of changes in the oxygen concentration measured by a polarographic oxygen electrode are described. In addition, some properties of ...
A valence force field for the amide group
(Elsevier, 1971-01)
A valence force field is presented for the grouping R-CO-NH-R' where R and R' are CH2 or CH3, derived from the frequencies of N-methylacetanide, nylons, and some of the deuteroderivatives. By refining all experimental data ...
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 ...
A complete general valence force field for secondary chlorides
(Elsevier, 1973-12)
A general valence force field for secondary chlorides has been refined which includes torsional force constants based on assignments of low frequency modes in model compounds. This force field also incorporates force ...
Assignment of torsion and low frequency bending vibrations of secondary chlorides
(Elsevier, 1973-10)
Far infrared and Raman spectra of 2-chloropropane, 2-chlorobutane and dl- and meso-2,4-dichloropentane have been analyzed in order to assign the torsional force constants in the valence force field for secondary chlorides. ...
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, ...
