CH₅⁺ is a fascinating highly fluxional cation that was highlighted in the July 25, 2005 issue of Chemical and Engineering News. You can access the article here.

The article mentions our group's work on the potential energy surface and calculation of the vibrational spectrum. We have also collaborated with Anne McCoy of the Ohio State University, who performed quantum Diffusion Monte Carlo calculations of the properties of the zero point state. You can find references to those papers here. You can also see CH₅⁺ in action by starting the mpeg.

Here is the latest paper on CH₅⁺ that describes its low resolution IR spectrum: Abstract or Full Text. The article appeared in the January 6, 2006 issue of Science.
