McLaffertyWandlungsmechanismus

McLaffertyWand is a fictional concept in chemical analysis that envisions a wand-like instrument to illustrate and influence McLafferty-type fragmentation in mass spectrometry. The concept is used in educational and theoretical contexts to explore how gamma-hydrogen transfer can lead to characteristic cleavage of carbonyl compounds, without asserting the existence of a real device.

Its name combines the chemist Fred McLafferty, who described the rearrangement that bears his name, with "wand"

In speculative designs, the device would connect to a mass spectrometer or ion source and employ controlled

Potential applications include classroom demonstrations of fragmentation mechanisms, hypothesis testing for structure elucidation, and didactic exploration

As a hypothetical construct, McLaffertyWand has not been described in peer-reviewed literature as a real instrument;
