[Effect of temperature on the modification of spectral properties of tryptophan aqueous solutions induced by water previously treated with laser radiation].
It was shown that preliminary exposure of a solvent (water) to low-intensity laser radiation reduces the tryptophan fluorescence intensity, and this fluorescence quenching effect is retained throughout the temperature range explored (from 8 up to 50 degrees C). The effects found are interpreted as resulting from changes in solvent properties induced by the action of electromagnetic radiation on interaction of water molecules with solute.
