| Polarised Raman spectroscopy (20–50 °C), mean non-coincidence effect of the O–H stretching band, water–ethanol series | a clear drop in NCE with every 20 % increase in the volume percentage of ethanol |
| Polarised Raman spectroscopy and MCR-ALS, change in enthalpy for hydrogen-bond weakening, water | 20.8 ± 4.1 kJ mol⁻¹ |
| Polarised Raman spectroscopy and MCR-ALS, change in enthalpy for hydrogen-bond weakening, 200 mM KCl aqueous solution | 16.2 ± 0.8 kJ mol⁻¹ |
| Polarised Raman spectroscopy and MCR-ALS, change in enthalpy for hydrogen-bond weakening, water–ethanol series | increases on addition of ethanol up to the 40 % sample and then decreases in the 60 % and 80 % samples |
| Polarised Raman spectroscopy and MCR-ALS, 200 mM KCl effect at 20 and 40 volume% ethanol | does not alter the ΔHHBW by a statistically significant value |
