The gaseous ion (CD3)2CF+, which is isoelectronic with acetone, has a stretching vibration in the resonant IR multiphoton dissocation (IRMPD) spectrum, indicating a high degree of double-bond character in the C![[BOND]](http://onlinelibrarystatic.wiley.com/undisplayable_characters/00f8ff.gif)
F bond (see picture). Absorption bands predicted by density functional calculations with anharmonic corrections (black line) agree well with the experimental spectrum.
