'How does a photon get into an atom?'This question puzzled not only leading scientists, e.g. Schrödinger and Heisenberg. It is still asked by students. And it is, indeed, a key question of quantum mechanics.James D. Macomber's book was the first to

Photolysis of the bond Rar–NO2 contributes to quenching of the fluorescence of aromatic nitro compounds. Since no nitro compound is known which fluoresces above 20,000 cm−1 photolysis must occur via a predissociation process. Either a fluorine-su

Umbelliferones (7-hydroxycoumarines) having phenyl-, ethoxycarbonyl-, cyano- or benzothiazolyl substituents in 3-position are excellent and water soluble laser dyes, emitting in the 440 to 525 nm region, when pumped with a frequency tripledQ-switch N

In nonpolar solvents p-diethylaminobenzoic acid ethyl ester presents multiple fluorescence. The considerable temperature and viscosity dependence of the fluorescence quantum yields as well as solvatochromic effects on the long wavelength fluorescence

The pH-dependent absorption and fluorescence spectra of 4-phenylumbelliferone (4-PU) are reported. 4-PU, which is a model for several natural compounds, shows an unusual behaviour in fluorescing due to a species formed in acidic solutions by an adiab
