“…If the electronic absorptions are situated in the far UV region, then
is a measure of the overall oscillator strength of the electronic transitions, that is, it is proportional to the number of C atoms. In addition, the position of the OH group also seems to be characteristic
[1,3,23–25] . Thus, the decrease of
as a function of N is more pronounced for tertiary alcohols than for primary or secondary ones indicating a higher oscillator strength and/or a stronger coupling of the solvent oscillators with those of the solute and consequently a stronger redshift in accordance with the previous study
