During the past year, we have used HERMON to begin creating a database of high resolution transition metal compound x-ray absorption spectra for use in applications involving environmental substrates. The applications are to remediation of contaminated soils, microbially induced bio-mineralization, and the surface chemistry of minerals and microscopic crystals in the environment. We are now in ...
[DOC File]Absorption Spectrum of Chlorophyll
https://info.5y1.org/absorption-spectra-database_1_15611c.html
Absorption spectra of chlorophyll a and b in diethyl ether. The purity of chlorophyll can be measured by the ratio of the absorbencies of the “blue” and “red” maxima. In an organic solution, chlorophyll has two absorption maxima in the visible spectrum with wavelengths shorter than 720 nm. The short-lived fluorescent state is produced by the excitation of either the blue or red ...

Mid-IR Sensors for Hydrocarbon Fuel Measurements
Quantitative absorption measurements require a database of temperature-dependent cross section data for the hydrocarbons of interest. Using a temperature-controlled absorption cell and a Nicolet 6700 FTIR spectrometer, we investigated the absorption spectrum of many important hydrocarbon compounds and practical fuel blends. Figure 2 shows an example temperature-dependent data for regular ...
[DOC File]Molecular rotational spectra formulae
https://info.5y1.org/absorption-spectra-database_1_1f9c3b.html
Absorption coefficients in terms of Einstein coefficients. Absorption coefficient per unit volumn of molecular gas is . From here on, the subscript “ul” of frequency has been omitted for clarity. Substituting Aul into this formula, one gets . Boltzmann distribution. In local thermal equilibrium (LTE), the molecular energy level population distribution nj obeys the Boltzmann distribution ...

The UV-visible absorption spectra were collected using Agilent 8452 Diode Array Spectrophotometer (Santa Clara, CA, USA) inside the glovebox. In sorption experiments, known volumes of Fe3-xTixO4 nanoparticle suspension and reduced MtoA were added to the Tris buffer solution mentioned above at desired pH. Nanoparticle concentration was fixed to give a concentration of 108 ± 4 μM Fe(II ...
INTRODUCTION TO INFRARED (IR) SPECTROSCOPY
This is an excellent Spectroscopy database web site that contains IR, MS, NMR and CNMR scans for many organic compounds. Alkanes ( CH3 @ 2960 & 2850 cm-1 and @ 1460 & 1380 cm-1
[DOC File]A few hints when using the NIST database:
https://info.5y1.org/absorption-spectra-database_1_bf7c96.html
Focus on two of the absorption regions in the spectra: ~1380 cm-1 and ~525 cm-1 . Notice the variability in intensity and appearance of the peaks in those two regions for the isomers. Mark these regions on the spectra on the next page. a) For the two IR spectra below, specify in the white space on the spectra, whether they contain an n-butyl, sec-butyl, isobutyl, or tert-butyl group. Circle ...
[DOCX File]5 Reflectance spectra and metadata: A database approach
https://info.5y1.org/absorption-spectra-database_1_b03fd2.html
The database structure has been custom designed to maximise cross referencing between spectra, photos and metadata. SSD required a system to account for and link the spectral and metadata standards implemented. A SQL server is used as a data warehouse to store all information. The spectra and photos are stored as binary files within the database. The metadata table contains information …
