摘要:

Carbon C-13 spin-lattice relaxation times, T1, of Serine, Threonine, Phosphoserine and Phosphothreonine have been measured in D2O at neutral pD. Changes in over-all motions under phosphorylation has been detected. Segmental motions are not affected by phosphorylation. With the aid of T1(C-13) values of other amino acids an empirical relationship between NT1 and molecular weights (Mw) is tested that seems valid also for small peptides. Such relationship allows to interpret results from T1 measurements with the aid of a simple spherical model.

摘要:

The surface of a P type Si wafer was bombarded with14N2+and H2+and the Raman spectrum of the implanted surface was obtained. The recorded spectrum not only confirms the information of various silicon-nitrogen, silicon-hydrogen, silicon-hydrogen-nitrogen-oxygen complexes but enables the identification of others.

摘要:

The Raman spectrum of the surface of a P-type silicon wafer bombarded with 30 KeV D2+has been re-investigated. The recorded spectrum not only confirms the formation of a-Si layer and various silicon, deuterium and hydrogen complexes, but enables the identification of others.

摘要:

As shown in a previous paper(1), the ethyl α-ketocyclopentylcarboxylate (hereafter HCBCP, according to its non-systematic name carbetoxycyclopentanone) easily undergoes a keto-enolic tautomerism, the enolic, de-protonized species thus forming coordination compounds with Mn(II), Fe(III), Co(II), Ni(II), and Cu(II). In addition to this bidentate ligand, the complexes usually contain coordinated water molecules, thus completing a distorted octahedral coordination around the metallic site. The immediate environment of the metal in these complexes is very similar to that existing in their acetylacetonate compounds, M(acac)n(n=2 or 3). Theseacacderivatives

摘要:

Excitation temperatures of atoms and ions and rotational temperatures of molecules have been investigated in a hollow cathode discharge under different experimental conditions. These temperatures have been found to be 3900–4300 K or 5200–5700 K for Fe I, 6100–7500 K for Ar I, 23000–29000 K for Ar II, 1400–2400 K for N2and 1000–2300 K for N2+.

摘要:

Some problems about registration of low intensity spectral lines by using photon counting method are discussed. Application of the MC6840 Programmable Timer in automated data acquisition systems is described. A microprocessor based automated system for registration of spectral lines with piezoelectrically scanned Fabry-Perot interferometer is described. Algorithms are shown.
