The cis, trans(lRS)-3-(2,2, 2-trichloroethyl)-2,2-dimethylcyclopropane earboxylate have been identified by ¹H-NMR obtained in the presence nf LSR Eu(fod)₃. The stereoconf iguration of substituted cyclopropane have been deiermined with coupling constants ³J=5.5Hz (cis) and 4Hz(trans). The observed limiting shifts and MoConell-Robertson equation have been used to determine resoaable molecular geometry parameters of the complex, from which the ratio of pssudocontact constants of the carbonyl groups in the two isomers have been calculated.

In this paper the NMR and the coupling of pnotons on the nitrogen atom and its neighbouring carbon atom in N-(3-substituted amino-4-chIorocinnamyl) -sec-butylamines, a kind of new compounds, were reported.The configurations of these compounds were assigned based on their ¹N-NMR, and confinmed by the X-ray diffraction results of one of these coznpounds.The coupling phenomenon of protons on the nitrogen and its neighbouring carbon in these compounds was confirmed by decoupling technique

Bleomycin A₆ is one of the compositions of bleomycin, which has selective influence on the membrane fluidity of mouse ascites hepatoma cells and it has no effect in marrow cell and liver cell of normal mouse. Bleomycin A₆ reduces the phase transition point from liquid crystal to liquid state of malignant cell membrane by 2℃. Synergistic effect of the bleomycin A₆ with continual hyperthermia was observed which could cause pronounced changes in the speed of membrane fluidity.

The primary processes in UV photolysis and photooxidatiou of 14 aromatic aldehydes have been studied by the combinatiou of spin trapping technique and ESR spectroscopy. The results show that:
1. The main active intermediates in photolysis of 10 substituted aromatic aldehydes are aromatic amido radicals ϕĊO.
2. Active radicals formed in the primary processes of photooxidation are the same as those formeb in the photolysis processes, and accumulation rates of free radicals in photooxidation are faster than those in photlysis. So it is sure that the formation of free radicals are accelerated owing to the hydrogen abstraction from aldehydes by oxygen.
3. No active radicals have been detected for OH substituted aromatic aldehydes.

Photoinduced electron transfet of aqueous and non-aqueous Cadmium Sulfide (CdS) dispersions in the presence of electron acceptors such as PQ⁺⁺ have been studied by means of ESR. The results show that upon irradiation of light (λ<517nm) the electron in the valence band (VB) of CdS can be excited to the conduction band (CB) giving rise to an electron-hole pair and the electron transfer from CB to PQ⁺⁺ to form free radical PQ⁺⁺ which can be detected by ESR.When electron donor such as EDTA is added to the systems, there is enhancement in the formation of PQ⁺⁺ which suggests that this hole is neutralized through the oxidation of EDTA.This returns the system to its original state thus allowing the CdS particles to be functional again in the photoproduction of PQ⁺⁺. Hence the CdS darticles are playing a catalytic role and in fact can be considered as a photocatalytic pump in which electrons are transfered from EDTA to PQ⁺⁺.

¹H-NMR technique was used to study systematically the additive products formed by the hydrosilation reactions of the unsaturated ester. The chemical shifts of ¹H-NMR spectra of the additive products were assigned. We advanced the method to calculate the percentage of the α-and β-species in the additive products. In contrast with chemical analysis method, the advantages of this method are rapid accurate and capalle to follow the changes of the structure of the reaction system.

The active radicals produced in the photolysis of substituted titanocene dichloride complexes (RC₅H₄)₂TiCl₂ (R=CH₃ C₂H₅, C₃H₇, C₅H₁₁, C₆H₁₁) have been studied by combination of spin trapping technique with ESR spectroscopy Results show that the primary process of photolysis is homolytic cleavage of the Ti-RC₅H₄ π bond, with the formation of (RC₅H₄)^· radical and (RC₅H₄) TiCl₂ fragment. The (RC₅H₄)^· radical can be trapped by nitrosodurene (ND) to form two spin adducts and their concentration ratio is about 1:1.

The interaction of insulin with phosphloipid vesicles as a model of biological membranes is studied by NMR technique.
Analysis of the spectra revealed that the B chain including hydrophobic surface at the insulin molecular surface may be insertrd into the phospholipid bilayer and perturbes the bilayer.
Neutral pH value range is the best binding condition of insulin with membrane.

Solid-state carbon-13 NMR linewidth of 1,2-polybutadienes with various contentsof 1,2-units were measured over a temperature range from-50℃ to 50℃. The structure and temperature dependences of the linewidth have been investigated. It is found that the NMR relaxation in polymers is dependent not only on the chain structure but also on the free volume. The free volume theory is also applicable to the NMR relaxation in polymers.

An indirect, but quite simple NMR method for measuring the formation constant of Ba²⁺ complex with 18-crown-6 has been developed. External referencing of intensities has been applied to measure the ¹⁹F intensities in saturated BaF₂ solutions in the presence or absence of the ligand substance.The formation constant pf Ba²⁺ complex with 18-crown-6 has been determined by this method.

A method for automatic measurement and calculation of self-diffusion coefficients on a standard pulsed FT-NMR spectrometer is presented. This method which is based on Fourier-transformed pulsed-gradient spin-echo technique is capable of simultaneously providing the self-diffusion coefficients of several components for a multicomponent system with a simplied operating proess.

In this paper a method based on additive C-13 shift relationships, using empirical substituent chemical shift paremeters, is described. It is applicable to aliphatic saturated hydrocarbons earring 45 functional groups as well as the carbons contained in these functional groups. It can also take care of alicyclic compounds, although it's accuracy tends to be lower. The computer program is written in FORTRAN IV-plus and BASIC, and run on a VAX 11/780, or a PDF 11/23, or a microcomputer IBM PC/XT etc.

An amplitude limited regenerative ¹⁴N NQR probe has been designed and built with field effect transistors. It has a frequency range of 1-5 MHz and a rf.amplitude range of 0.5-4 Vpp. In order to obtain a digital record system for NQR spectral lines, a microprocessor Z-80 is used to construct a phase sensitive detection system. By connecting this digital PSD system to the probe circuit through a signal processing channel, a regenerative ¹⁴N NQR spectrometer with microprocessor is constructed. The ¹⁴N NQR spectral lines of some compounds as hexa-methylenetetramine, sodium nitrite, urea etc. have been observed at room temperature and 77K with the spectrometer. The experiment results show that the s/n racio of NQR spectrometer with microprocessor is twice as large as one without microprocessor. Additionally, this instrument may provide a convenience for the further processing data.

The autoregressive spectral estimates of the SMMW Fourier transform spectroscopy data were presented.The modified interferogram was used for the linear prediction with the autoregressive model.Due to the elimination of the "window" effect,the resolution exceeds the value set by the FFT.The procedure of AR spectral estimates and the results were presented.Experimental results show that,this method provides four times higher resolution in the spectrum than the Fourier transform spectrometer does.
