The vibrational spectrum of 2,6-naphthyridine (point group C 2 h ) has been measured; the fundamentals are assigned. The electronic spectrum is recorded to 210 nm in solution, and the first two absorption regions studied in further detail. The first

The low-energy absorption system of dibenzofuran vapour has been re-measured at high resolution. The origin band (O) and the prominent band at O + 445 have different contours, and so have opposite polarization. In the solid state, the frequency of th

Detailed spectroscopic observations on the first 1 n, π * states of three different N-heterocycles are successfully modelled through vibronic coupling calculations incorporating a small number of adjusted but non-arbitrary parameters: in pyridine, t

The bond-stretching vibrations of H2O, NH3 and SO2 (also HDO and D2O) are treated computationally according to a model in which the bond oscillators are Morse oscillators, coupled only through a mass and bond-angle dependent kinetic-energy term. Each

A valence force field, including selected interaction constants, has been used to compute the thirty-three planar vibration frequencies of each of naphthalene, naphthalene-α-d4, naphthalene-β-d4 and naphthalene-d8. Starting with benzene-like force

The vibrational structure of the absorption spectrum of azulene near 3500 A (to the second excited singlet state, B is markedly altered by changing the molecular environment, even though the corresponding emission spectrum remains largely unchanged.

The first two electronic transitions of azulene have been photographed in the vapor, and the first transition in the pure crystal as well (4°K). The pure crystal spectrum is very diffuse; this is attributed to the disordered structure of the crystal
