Absorption Spectra of the Ethyl Chlorophyllides
Nature, 1953THE spectra of the ethyl chlorophyllides, the crystalline derivatives of chlorophyll by replacement of the phytyl by the ethyl radical, are of interest as these compounds are valuable as actinometry standards in the study of the efficiency of photosynthesis.

Absorption Spectra of Exciplexes
The Journal of Chemical Physics, 1971Absorption spectra of the exciplexes of pyrene, anthracene, biphenyl, and naphthalene with diethylaniline (DEA) as a common electron donor are recorded by applying pulse laser photolysis. The numerous bands appearing in the spectra are analyzed and attributed to transitions from the emitting charge-transfer state, (A−D+), to higher excited charge ...

Absorption Spectra of Aldehydes
Nature, 19341. RECENT observations of the ultra-violet absorption bands in the vapours of a series of homologous aldehydes have disclosed a vibrational structure, which is very similar throughout the series, since 35 measurements have given an average separation of 1025 cm.-1 in the spectra of the higher homologues, although this interval increases to 1053 cm.-1 ...

Intensification of Absorption Spectra
Nature, 1963Keilin and Hartree1 have described the sharpening and intensification of absorption spectra of haem compounds which occurred on making the observation at liquid air temperature. They observed that the intensification was due to light scattering by the ice crystals and could be duplicated by placing the cytochrome in a kaolin suspension.

[Fluorescence spectra and absorption spectra of carvacrol].
Guang pu xue yu guang pu fen xi = Guang pu, 2015Fluorescence spectra and absorption spectra of carvacrol, an active component of Chinese herbal medicines, have been studied. The ionization constant and fluorescence quantum yield of carvacrol were measured according to spectral data. Under the condition of pH < 2.0, fluorescence intensity of carvacrol increases with the increase in pH value.
