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 ...
Vibrational analysis of peptides, polypeptides, and proteins. XXXII. Α-Poly( L -glutamic acid)
(Wiley Subscription Services, Inc., A Wiley Company, 1985-08)
The Raman and ir spectra of Α-helical poly( L -glutamic acid) have been assigned on the basis of a normal mode calculation for this structure. The force field was based on our previously refined main-chain force constants ...
Synthesis of fused pyrrolines by the intramolecular cycloadition of azides application to the pyrrolizidine alkaloids.
(Elsevier, 1985)
Intramolecular 1,3-dipolar cycloaddition of azide 4 proceeds through triazoline 5 and vinyl aziridine 6, resulting in the formation of the 1,5-homodienyl shift product 7 and the tetrahydropyrrolizines 8 and 9. Compound 8 ...
Laser optogalvanic spectroscopy of molecules: The red electronic system of titanium oxide (TiO)
(Elsevier, 1985-02-08)
The laser optogalvanic (LOG) spectrum of the (0,0) bands of the B 3[Pi] 3[Delta] transition of titanium oxide (TiO) has been observed. The TiO molecules were generated in a glow discharge by sputtering titanium metal and ...
Raman and normal mode studies of the polypeptide chain conformations in crystalline magnesium and calcium poly(-glutamate)s
(Elsevier, 1985)
An analysis of the Raman spectra of dry crystalline magnesium and calcium poly(-glutamate)s, based on a normal mode calculation of [alpha]-helical poly(-glutamate), shows that the polypeptide chains in both salts have an ...
The thermal diffusivity and conductivity of transformation-toughened solid solutions of alumina and chromia
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1985-07)
The thermal diffusivity of a series of solid solutions of alumina and chromia transformation toughened with a dispersed phase of unstabilized zirconia was measured by means of the laser-flash method from room temperature ...
Spectroscopic study of Α- and Β-phase isotactic polypropylene and of atactic polypropylene in solution
(John Wiley & Sons, Inc., 1985-12)
No Abstract.
Thermodynamics of thallium alkanoates I. Heat capacity and thermodynamic functions of thallium(I) n-hexanoate
(Elsevier, 1985-05)
The sub-ambient heat capacity of thallium(I) n-hexanoate is characterized by transitions at 203.5 and 208.3 K which show Cp, m/R maxima of about 400 and 2500 and ([Delta]Sm/R)'s of 1.03 and 1.07. Both appear to be essentially ...
Effects of partial closure and friction on a radial crack emanating from a circular hole
(Kluwer Academic Publishers; Martinus Nijhoff Publishers ; Springer Science+Business Media, 1985-05)
A radial crack emanating from a circular hole in an infinite sheet under tension is considered. Depending on the crack length and location, the crack may be partially or completely open or closed. In case of closure, ...
