What important information about a compound can be obtained from a mass spectrum and how is it used? What fragments might you expect in the mass spectra of the compound shown below? What is spectroscopy? what would distinguish the mass spectrum of 2,2-dimethylpropane from those of pentane amd...
Relative ion current (signal) is plotted versus m/z producing a mass spectrum. Small molecules typically exhibit only a single charge: the m/z is therefore some mass (m) over 1. The ‘1' being a proton added in the ionization process [represented M+H+ or M-H- if formed...
In the broadest sense a spectrometer is any instrument that is used to measure the variation of a physical characteristic over a given range; i.e. a spectrum. This could be a mass-to-charge ratio spectrum in the case of a mass spectrometer, the variation of nuclear resonant frequencies in...
Mass spectrometry (MS) is an analytical laboratory technique to separate the components of a sample by theirmassand electrical charge. The instrument used in MS is called mass spectrometer. It produces a mass spectrum that plots the mass-to-charge (m/z) ratio of compounds in a mixture. ...
A spectrometer is a device that measures a continuous, non-discrete physical characteristic by first separating it into a spectrum of its constituent components.

Men also expressed a desire for volume and variety in their sexual lives, and for sex that is free from physical, social or psychological harm. Comparative analysis identified that older men were less likely to idealise a relationship or emotional connection, but were more likely to specify the...
