Solvatochromism of â-Naphthol

Excitation and emission fluorescence spectra of 2-naphthol and 2-methoxynaphthalene were measured in a series of pure solvents. The spectral shifts are correlated by the Kamlet-Taft parameters (π*, â, and R). As judged from the π* dependence, both molecules have a negligibly small dipole moment in their ground electronic state, which increases in the excited (S1) state. However, the majority of...

Terahertz spectroscopy of naphthalene, a-naphthol, b-naphthol, biphenyl and anthracene

The far-infrared THz spectra of naphthalene, a-naphthol, b-naphthol, biphenyl and anthracene have been measured using THz time-domain spectroscopy. The low-energy vibrational modes of measured molecules are discussed based on their characteristic and common features. The complex dielectric functions are obtained. Meanwhile, it is shown that the experimental results can be well fitted by a stand...

2,4-Dinitro-1-naphthol

In the title compound, C(10)H(6)N(2)O(5), the two fused rings are almost co-planar, with an r.m.s. deviation of 0.0163 Å. The nitro groups are oriented at dihedral angles of 2.62 (11) and 44.69 (11)° with respect to the plane of the parent fused rings. Intra-molecular O-H⋯O and C-H⋯O hydrogen bonds complete S(6) ring motifs. In the crystal, mol-ecules are linked into chains along [101] by inter...

1-(Hydroxy­imino­meth­yl)-2-naphthol

The title compound, C(11)H(9)NO(2), was prepared by a condens-ation reaction of 2-hydr-oxy-1-naphthaldehyde with hydroxyl-ammonium chloride in refluxing ethanol. An intra-molecular O-H⋯N hydrogen bond is observed. In the crystal structure, inter-molecular O-H⋯O and C-H⋯O hydrogen-bond inter-actions result in a two-dimensional network.
