[Octane] The mass spectrum of 2-hexanone shows a 'McLafferty fragment' at m/z = 58, while the propene fragment is not observed because it is a neutral species (remember, only cationic fragments are observed in MS).
An alcohol's molecular ion is small or non-existent. In mass spectrometry, the alpha position is the atom next to the atom that has the single electron or radical. Though there are treatments which can ease and help to manage symptoms, MS is a condition which has no cure MS: Get the latest Morgan Stanley stock price and detailed information including MS news, historical charts and realtime prices. Mass spectrometry (MS) is a powerful analytical technique widely used by chemists, biologists, medical researchers, and environmental and forensic scientists, among others. LC-MS/MS data is composed of time series of individual full scan MS1 spectra, interspersed by one or more MS/MS spectra.

A number of legal tech startups are eager to not only help lawyers, but automate some of the processes bogged down by pen and paper. Many of these new developments will be described in detail in other chapters of this book; however, basic aspects of some of the key enabling technologies will be briefly reviewed here, including electrospray ionisation, common mass analysers, and ion mobility spectrometry.
