This blue shift roughly gives the hydrogen bond energy in the $S_{1}(nx^{\ast})$ of $2740 cm^{-1}$. Our interpretation to the short lifetime is that due to the large stabilization of the hydrogen bond, the $S_{1}$ is below $T_{2}(xx^{\ast})$. which breaks down the coupling between them, resulting in the quenching of the slow component of fluorescence en_US dc.format.extent 81438 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title HYDROGEN BONDING IN GROUND AND EXCITED STATES OF PYRAZINE en_US dc.type article en_US
