A kind of submillimeter waves Fourier transform spectrometers is presented. The working wavelength is in the region of 33 to 500 micron. The resolution is 1 cm^-1. A microcomputer is used for the data acquisition and data processing. The moving mirror is driven by a liquid-pressure machine in order to get even smooth moving. The displacement of the moving mirror is measured with a laser interferometer. The optical path system is evacuated to prevent the absorption of water-vapour.

Proton paramagnetic shifts of Ln(pic)₃ (Ln=rare earth ions except Pin and Gd, pic=picric acid) hare been measured. The shift direction of the whole series shows a "tetrad effect". It can be well explained by the "tetrad rule" of 4f electron clouds. The configuration of Ln(pic)₃ complex in acetone solution is discussed. The theory of pseudocontact shift is also discussed.

The ¹³C-NMR and ¹H-NMR spectra of nine benzo-15-crown-5 are recorded. Comibned with microanalyses, infrared, ultraviolet and mass spectroscopy data, the molecular structures of the crowns are determined. All the ¹³C-NMR spectral lines are assigned based on the line positions and splittings as well as substituent inductive effects. The influences of benzine ring's different sub-stituets on the chemical shifts of crown's carbons are also discussed.

The distribution of hydrogen isotope-Deuterium in alcohol is determined by natural abundance Hyolrogen-2 Nuclear Magnetic Resonance, It is found that the content of Deuterium will be varied with different quality of water, And the deuterium conteut in methylene group varied more largely than in methylene group, But the difference of deuterium content of alcohol making with differeut material is shown predominantly in methyl group, Thus We obtained a significant method for monitoring quality of making compound and studing biochemical mechanism.

The mutual influence between different microwave transitions in optical pumping experiment is observed. The possibility of applying the Optical-microwave pumping device in gas cell is discussed.

Optically detected magnetic resonance (ODMR) technique has shown to be a successful tool for research work on the impurities and defects in semiconductors. This method may provide detailed information about the electronic structure of the impurities and defects and the relation between them and the tr-asition processes. The technique of ODMR, especially the new developments and understanding in last few years, has been discussed in this paper. The application of ODMR to the research field of impurities and defects and radiation processes in Ⅱ-V semiconductors has been reviewed and the research work about InP;Mn and GaP:O has been discussed as examples in detail.

In this paper, the identification of eight title compounds (Monolactam derivatives) new synthesized have been made by 360MC ¹H-NMR spectra. The stereoconfiguration of monolactam ring has been proved with coupling constant. Through the resolution of the spectra data in detail, all synthesized compounds have been conclttsed to be cis-monolactam derivatives The essential information have not been got from 80MC ¹H-NMR spectra.

In the present paper the calculation method of proton chemical shifts in the rings of fused benzenoid hydrocarbons and its berivatives and in its alkyl chains has been proposed.
The fused benzenoid compounds must be presented by Kckul'e formulas, and the proton chemical shifts of its rings can be calculated by following formula:
δ=σ_j.c-c+σ_mi.ci
σ_j.c-c are the effects of various ethenyls σ_mi.ci are the net ring-current effe-cts of six electrons orbitals of various benzene rings, and its calculation formula is:
σ_m.e=(1/2) ^m×1,52 m=n-u
The m are sim the order numbers of the net ring-current effects,and equal to the bond number n from the proton to the benzene ring minus the cis-form bond number u.
As concerns protons in 4. 5 positions or 9,10 positions, of phenanthrene ring and analogous phenanthrene rings,the phenanthrene ring effect must be used. As concerns protons in coronene ring, the coronene ring effect be used. And as concerns protons in the compounds ring with displaced groups, the group effects be used.
The calculation formula for the protons in the ring's alkyl chain is:
δ=σ_p.CH3+ασ_2.CH3+βσ_t.CH3+σ_i.G
This formula has been reported in the former article of this author.σ_i,G is a certain order effect of fused benzenoid radical.

The fundamental principle and experimental technique of selective excitation are presented.

³¹P NMR spectroscopy was used to identify various alkyl dialkyl phosph-onates and acetoallyl dialkylphosphonates. Quantitative results were also obtained to correlale with conditions of preparation and purity of products.
Two steric structures of cyclic adenosine-3',5'-phosphates identified as well.³¹P chemical shift of axial and equatorial form differ by 2ppm.
