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 dc.format.extent 108539 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE ELECTRONIC SPECTRUM, MOLECULAR STRUCTURE, AND QUANTUM BEAT SPECTROSCOPY OF GERMYLIDENE $(H_{2}C=Ge)$, THE SIMPLEST UNSATURATED GERMYLENE en_US dc.type article en_US
