Spectrochemistry is the application of spectroscopy in several fields of chemistry. It includes analysis of spectra in chemical terms, and use of spectra to derive the structure of chemical compounds, and also to qualitatively and quantitively analyze their presence in the sample.
The reagent removes pairs of H atoms from organic molecules. The stoichiometry of its action is illustrated by the conversion of tetralin to naphthalene: . 2 C 6 Cl 2 (CN) 2 O 2 + C 10 H 12 → 2 C 6 Cl 2 (CN) 2 (OH) 2 + C 10 H 8
A spectrochemical series is a list of ligands ordered by ligand "strength", and a list of metal ions based on oxidation number, group and element.For a metal ion, the ligands modify the difference in energy Δ between the d orbitals, called the ligand-field splitting parameter in ligand field theory, or the crystal-field splitting parameter in crystal field theory.
The company's products are sold under the brand names of Thermo Scientific, Fisher Scientific, and several other recognized brand names (e.g. Applied Biosystems, Invitrogen, Patheon, PPD, and Nalgene). According to company figures, as of 2007, 46% of its sales were in life sciences, 20% in healthcare, and 34% in industrial/environmental and safety.
Methyl trifluoromethanesulfonate, also commonly called methyl triflate and abbreviated MeOTf, is the organic compound with the formula CF 3 SO 2 OCH 3.It is a colourless liquid which finds use in organic chemistry as a powerful methylating agent. [2]
