Abstract

Helium nanodroplet spectroscopy is a well-established experimental technique to study weakly bound complexes and reactive species. The superfluid helium interacts weakly with the embedded species, leading to only small matrix-induced shifts in vibrational spectra. This technique has been applied for the spectroscopic study of the resonance-stabilized allyl radical and its reactions and complexes.footnote{C. M. Leavitt, C. P. Moradi, B. W. Acrey, G. E. Douberly; J. Chem. Phys. 2013, 139, 234301.}$^{,}$footnote{D. Leicht, D. Habig, G. Schwaab, M. Havenith; J. Phys. Chem. A 2015, 119, 1007.} The tropyl radical is another example of a $pi$-conjugated radical, being of importance as a reaction intermediate in organic chemistry. Having an electron in a pair of degenerate orbitals, its geometry is subject to the Jahn-Teller effect.footnote{E. P. F. Lee, T. G. Wright; J. Phys. Chem. A 1998, 102, 4007.} The Jahn-Teller distortion of the ground electronic state is probed with IR laser spectroscopy.
