Fluorescence and UV-visible absorption spectra of HPTS (8-hydroxy-1,3,6-pyrenetrisulphonic acid trisodium salt, pyranine) were measured in a variety of solvents. Fluorescence maxima (in kcal mol -1 ) can be correlated with the Kosower Z parameter (r = 0.901), the Dimroth-Reichardt E T (30) parameter
Cooling of aromatic amines in nonpolar media shows 3 disappearance of the absorption CT band. This diwppeuante suggests the existence of a different conformation of these molecules in the stiffening range.
The effects of variation of temperature in the range o"-40°C on the zero and second derivative ultraviolet absorption spectra of ten compounds have been investigated. When the temperature of the solutions was increased, most of the substances showed a linear reduction of maximum absorbance (A,,;,,),
