dc.description.abstract Laser-induced fluorescence (LIF) and dispersed fluorescence (DF) spectra of the cycloheptatrienyl (tropyl) radical (C$_7$H$_7$) have been observed under supersonic jet cooling conditions. The DF emission was collected by pumping different vibronic bands of the $\tilde{A}^2$E$_3^{\prime\prime}\leftarrow \tilde{X}^2$E$_2^{\prime\prime}$ LIF excitation spectrum. Analysis of the DF spectra yields valuable information about the vibrational levels of the ground $\tilde{X}^2$E$_2^{\prime\prime}$ electronic state. In addition to the experimental work, \textit{ab initio} calculations have been performed providing ground and excited state Jahn-Teller parameters; a comprehensive analysis reveals Jahn-Teller activity in 4 $e_3^{\prime}$ modes for the $\tilde{X}^2$E$_2^{\prime\prime}$ state and 3 $e_1^{\prime}$ modes for the $\tilde{A}^2$E$_3^{\prime\prime}$ and provides values for their vibrational frequencies as well as linear Jahn-Teller constants. In addition to the magnitude of the Jahn-Teller distortion, the stabilization energies for both electronic states have been calculated at the CASSCF(7,7) and EOMEA-CCSD levels of theory using different basis sets. en_US
