摘要：
The effect of hydrogen bonding, taking diethyl ether (Et2O) as the hydrogen-bonding partner, on the dual emission of salicylic acid (SA) has been investigated with both steady-state and time-domain experiments. It has been observed that in place of dual emission, only a single fluorescence band is observed int he presence of Et2O. This has been attributed to the fact that all SA molecules are converted into hydrogen-bonded complexes. Further, two configurations for the SA-Et2O complexes are suggested to explain the dynamical behaviour at low temperatures. © 1990.
