V. Bekarek et al., EFFECT OF MEDIUM ON THE ELECTRONIC-SPECTRA OF 2-NITROANILINE DERIVATIVES, Collection of Czechoslovak Chemical Communications, 61(1), 1996, pp. 155-159
The wavenumbers of the long-wavelength absorption band were measured f
or nine 4-substituted and 5-substituted derivatives of 2-nitroaniline
in the gaseous state and in 13 solvents where only nonspecific solvent
-solute interactions can be expected. For the series involving all the
solvents used, the solvent effects can be well expressed by an one-pa
rameter equation involving the product of the Born functions of the re
lative permittivity and of the refractive index of the solvent. For th
e series involving the nonpolar solvents and the gaseous state only, t
his equation reduces to an one-parameter equation involving the refrac
tive index Born function squared.
