웹2024년 8월 18일 · The tallest line in the stick diagram (in this case at m/z = 43) is called the base peak. This is usually given an arbitrary height of 100, and the height of everything else is measured relative to this. The base peak is the tallest peak because it represents the commonest fragment ion to be formed - either because there are several ways in which it … http://contents.kocw.or.kr/KOCW/document/2014/Duksung/leejaein/10.pdf

The ion at m / z 164 (M+163) might be due to the formation of 1-(4-fluoro-phenyl)-but-3-en-1-one (decarboxylation followed by the unsaturation of 4-fluoro benzyl butyric acid), which is a reduced fragment of benzyl butyric acid.
웹2024년 1월 19일 · Note: The presence of the carbon-13 isotope in a molecular ion causes a little peak 1 unit to the right of the M+ peak. This is called the M+1 peak. The presence of a chlorine atom in a compound causes two peaks in the molecular ion region - the M+ peak and the M+2 peak depending on whether the particular molecular ion contains a chlorine-35 or ...
