Sources of data
The overwhelming majority of spectra are taken from original
scientific papers with the precise references. Some of the data are
taken from several published collections. These collections include:
- "Atlas of spectra of aromatic and hetrocyclic
compounds", Koptyug, V.A. (editor), Science, Siberian
Department of AS USSR, Novosibirsk, volumes 28-35 (1984-1986).
- "Absorption spectra in the visible region", Lang,
L. (editor) volumes 1-20, Budapest, 1959-1975.
- "UV atlas of organic compounds", published in
collaboration with the Photoelectric Spectrometry Group, London, and
the Institute for Spectrochemie un Angewandte Sspectroskopie,
Dortmund, volumes 1-5, London, Butterworths and Weinheim, Chemie,
- "Ultraviolet absorption spectra of aromatic
hydrocarbons", Kusov, M.M., Shimanko, N.A., and Shishkina, M.V.,
AS USSR, Moscow.
- "Ultraviolet absorption spectra of heteroorganic
compounds", Bol'shakov, G.V., Vatago, V.S., and Agrest, F.B.,
Chemistry, Leningrad Department, Leningrad, 1969.
No data was used from "Ultraviolet spectra of aromatic
compounds", Friedel, R.A., and Milton, M.O., U.S. Bureau of
Mines, Bruceton PA, John Wiley and Sons, New York, 1951. 60 of the 600
substances in the publication were examined and found to often be
different from spectra in later literature and have narrower
- The UV/Vis
spectra collected are taken mainly in the liquid phase (this
reflects the nature of the literature the spectra are abstracted
from). Consequently the data on the solvent used are included. In
some rare cases when data published were obtained in the gas or
vapor phases just such spectra were included in the collection.
- It is typical for literature on UV/Vis spectra to contain a
shortened form mentioning only absorption for some spectra plot
peculiarities (couples of logarithm ε and wavelength). Data
are only used if the source contains a spectrum in graph form or (a
very rare case) a detailed digital form.
- For the X and Y axes, nm and logarithm ε (the logarithm
is base 10) are accepted as being used predominately in the recent
literature for UV spectra presentation. Any other units, were
recalcualted to match this convention. If the absorbency data in
a literature source can not be presented in quantitative form, the
source was omitted.
- The spectrometer used is described strictly as stated in the
original paper. The effective spectral resolution claimed for the
measurements is treated likewise.
- UV ID
- Registry number in the UV/Vis data collection.
- MELTING POINT
- Celsius scale data, updated with information from CRC Hanbdbook of
Chemistry and Physics, David R. Lide (Editor-in-Chief),
78th edition 1997-1998, CRC Press, Boca Raton, FL.
- BOILING POINT
- Same as melting point data. Abbreviations "sub."
and "dec." mean sublimation and decomposition.
- As stated in the original source. When only pH is indicated it
means the solvent is water. The abbreviation "n.s.g."
means no data about the solvent are given in the original source.
- As stated in the original source. Abbreviation
"n.i.g." means no data about the instrument are given in
the original source.
