dc.description.abstract Strong $S_{2} - S_{0}$ fluorescence has been observed in LIF spectra of jet-cooled germylidene, $H_{2}C=Ge$, produced by fragmentation of tetramethylgermane in a pulsed discharge. The ground and excited state molecular structures have been obtained from rotational analyses of the $0^{0}_{0}$ bands of $H_{2}C^{74}=Ge$ and $D_{2}C^{74}=Ge$. The vibrational structure of the spectrum is much more complicated than expected due to the prevalence of both vibronically induced bands and bands involving even quantum number changes in antisymmetric modes. The fluorescence decays of single rotational levels of the $0^{0}_{0}$ band of $H_{2}C^{74}=Ge$ exhibit molecular quantum beats for about 70\% of the levels surveyed. Density of states arguments show that most of the beats originate from interactions with high rovibronic levels of the ground state, although accidental coincidences with excited triplet state levels also occur. en_US
