  2. Spectroscopic notation - Wikipedia

    en.wikipedia.org/wiki/Spectroscopic_notation

    This notation is used to specify electron configurations and to create the term symbol for the electron states in a multi-electron atom. When writing a term symbol, the above scheme for a single electron's orbital quantum number is applied to the total orbital angular momentum associated to an electron state.

    where log(k s /k CH 3) B is the ratio of the rate of the base catalyzed reaction compared to the reference reaction, log(k s /k CH 3) A is ratio of a rate of the acid catalyzed reaction compared to the reference reaction, and ρ* is a reaction constant that describes the sensitivity of the reaction series. For the definition reaction series, ρ ...

    en.wikipedia.org/wiki/Mass_spectral_interpretation

    Electron ionization mass spectrum of the steroid alcohol brassicasterol. Mass spectral interpretation is the method employed to identify the chemical formula, characteristic fragment patterns and possible fragment ions from the mass spectra. [1] [2] Mass spectra is a plot of relative abundance against mass-to-charge ratio.

    It supports DIA-based profiling of PTMs, such as phosphorylation and ubiquitination, new technologies such as Scanning SWATH [36] and dia-PASEF, [37] and can perform library-free analyses (acts as a database search engine). [38] FlashLFQ Open source: FlashLFQ is an ultrafast label-free quantification algorithm for mass-spectrometry proteomics. [39]

  6. Acid–base reaction - Wikipedia

    en.wikipedia.org/wiki/Acidbase_reaction

    In chemistry, an acidbase reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acidbase theories, for example, Brønsted–Lowry acidbase theory.

    Democrats lost Nevada in the presidential race for the first time in 20 years, with Donald Trump defeating Kamala Harris, but the party feels it has a strong roadmap to win again in 2028.

  8. Hammett acidity function - Wikipedia

    en.wikipedia.org/wiki/Hammett_acidity_function

    The Hammett acidity function (H 0) is a measure of acidity that is used for very concentrated solutions of strong acids, including superacids.It was proposed by the physical organic chemist Louis Plack Hammett [1] [2] and is the best-known acidity function used to extend the measure of Brønsted–Lowry acidity beyond the dilute aqueous solutions for which the pH scale is useful.
