Table 1 Slopes m1 and m2 determined using respectively the plot of Stokes shifts against function F1(ε,n) and the plot of (\({v}_{a}\) + \({v}_{f}\))/2 against \({\mathrm{F}}_{2}(\upvarepsilon ,\mathrm{ n})\).

  1. Slope m was determined using the plot of Stokes shifts against function \({\mathrm{E}}_{\mathrm{T}}^{\mathrm{N}}\) along with ground-state dipole moment \({\upmu }_{\mathrm{g}}\), excited-state dipole moment \({\upmu }_{\mathrm{e}}\), change in dipole moment ∆μ, number of points and correlations factor r2 determined for both positions of maximum absorbance (I ~ 320 nm and II ~ 286 nm) for NTBD.
