Abstract
The electronic structure of the low-temperature phosphorescencent prob e 6-thioguanine was investigated. Structural transitions in some alcoh ols (ethanol, glycerol, propanediol) were obtained using this probe in the range 4.2-273 K. Aqueous solutions of native and denatured DNA an d those of native DNA with propanediol and DMSO added were studied in the range of 4.2-273 K. The analysis of the luminescence spectra of DN A solutions permits the assumption of the energy transfer to the probe on vv radiation of DNA. (C) 1994 John Wiley & Sons, Inc.
