菠菜和苏州青类囊体溶液的光谱特性

通过分析不同波长光激发下菠菜(Spinach)和苏州青(Suzhou Green)类囊体溶液的发射光谱和荧光光谱,以及同一波长下磁场处理前后类囊体溶液的光谱变化,探讨了低强度稳恒磁场对类囊体溶液的作用机理.结果表明,类囊体溶液中形成了大量的氢键,磁场处理前菠菜和苏州青的氢键喇曼散射峰为531 nm和533.2 nm,两者光系统II(PSII)荧光分别在689.8 nm和686 nm;磁场处理后两者的喇曼散射峰变为532.8 nm和532.4 nm,PSII荧光变为686.8 nm和685.4 nm.磁场改变了两样品中氢键键能,使其趋于相等.

Spectral Properties of Thylakoid Solutions of Spinach and Suzhou Green

The mechanism of the static low magnetic field action on thylakoid solutions was studied by analyzing the Raman spectra and PSII fluorescence of the spinach and Suzhou Green both excited by the light with different wavelength and to the changes in the spectra of the two samples treated by different magnetic fields with the same excitation wavelength. The results indicated that there were a lager number of Hydrogen bonds in the thylakoid solution. The Raman spectra were 531 nm and 532.2 nm and the PSII fluorescence were 689.8 and 686 nm for the spinach and Suzhou Green solution before the treatment by magnetic field. But the Raman spectra changed to 533.2 nm and 532.8 nm, and the PSII fluorescence were 686.8 nm and 685.4 nm for the two sample after the treatment. The static low magnetic field can change the Hydrogen bond energy to a constant value in the two solutions.
