It is shown that luminescence spectra of DNA, total histone (TH) and nucleohistone (NH) are the same under UV and VUV excitation. The luminescence quantum efficiency falls with a decrease of excitation wave length to 120 nm. This effect is connected

Photoemission of thin films of uracil, citosine, timine, adenine, quanine, DNA, RNA, nucleosides, nucleotides in the spectral region 125-250 nm is investigated. Photoemission work functions are determined, their values are in the interval of 5.7-6.1

The action of VUV and far UV (lambda greater than 240 nm) radiation of aqueous solutions of total histone by means of electrophoresis method is compared. By VUV photolysis the more effective destruction of HI and HIA histone fractions is determined.

The absorption spectra of thin films of nucleic acids, nucleosides, nucleotides, D-ribose, Na3PO4 in vacuum ultraviolet region are measured. In the spectral region 280--160 nm the absorption spectra consist of the bands of nucleic acid bases. In the

On the basis of the known photodimerization of uracil it is proposed to use its films obtained by sublimation in vacuum for the dosimetry of genetically active UV radiation. Experimental estimations are presented of radiation dose rate resulting in a

Electronic absorption spectra of thin films of chromatin and chromatin components in ultraviolet (140-280 nm) were investigated. The absorption coefficients mu (lambda) of chromatin, nucleosomes with and without histone H1, total histones (TH), DNA w
