Electron spectroscopy Study guides, Class notes & Summaries

Allows us to determine the molecule mass and the molecular formula of a compound, as well as some of it's structural featuresMass Spectrometry Tells us the kinds of functional groups a compound hasInfrared (IR) Spectroscopy Provides information about the carbon-hydrogen framework of an organic compoundNuclear magnetic resonance (NMR) spectroscopy A very small sample is placed in a mass spectrometer, where it is vaporized and then ionized (electron removed from each molecule). Electron ...

CHEMISTRY A LEVEL WITH SATISFIED SOLUTIONS What are the two elements which are exceptions to the electron configuration? - CORRECT-The two exceptions for this is copper and chromium. In both cases, the 4s subshell contains only one electron, even though there are electrons in the 3d subshell. To explain this, its because the 3d subshell is more stable when it is either half full, or completely full. So in the case of chromium, by having only one electron in the 4s subshell, ...

Why is the GC so commonly used in cooperation with a Mass Spectrometer? - ️️These two components, used together, allow a much finer degree of substance identification than either unit used separately. It is not possible to make an accurate identification of a particular molecule by gas chromatography or mass spectroscopy alone.Sometimes two different molecules can also have a similar pattern of ionized fragments in a mass spectrometer (mass spectrum). Combining the two processes reduces the ...
