Figure 3. v (peak maxima) dependence on (1/μ) of EtOH, as concentration of EtOH changes from 20 wt% to 100 wt%.

The dipole moments correspond to mixture concentrations in experiments as derivable from ref. 24 presented in a normalized scale. (a) peak maxima from PMCDS experiments. Normalized peak maxima vs normalized (1/μ) follows a power law relation as shown, with least square of 92% for anti and 97% for gauche conformer. (b) Peak maxima for this figure are related to ATR-FTIR spectrum. Normalized peak maxima relation with normalized (1/μ) follows the linear relation shown, with least square of 87% for anti and 97% for gauche conformer. The 20 wt% data point was excluded for linear fitting of the anti conformer due to high enthalpies of mixing for this concentration.
