The effect of high pressure up to 2400 bar on the UV–Vis spectra of three azo dyes, Acid Red 266 (AR), Benzopurpurine 4B (BP) and Congo Red (CR), in ethane-1,2-diol and water was investigated. The pressure dependences of the wavenumbers at maximum absorbance, νmax(p), recorded in both solvents, were determined and from those the corresponding gradients,
