 Title: THE $S_{1} \leftarrow S_{0}$ FLUORESCENCE EXCITATION SPECTRA OF ANISOLE AND STYRENE UING HIGH RESOLUTION TECHNIQUES Creators: Ribblett, Jason W.; Pratt, D. W. Issue Date: 1997 Abstract: Anisole (methoxybenzene) and styrene (vinylbenzene) are similar chemical species. However, their electronic strucures are very different. In this report, we describe the rotationally resolved fluorescence excitation spectra of the $S_{1} \leftarrow S_{u}$ origin bands of anisole and styrene. Both spectra are similar in overall appearance. However, a detailed analysis of the two spectra shows that the $S_{1} \leftarrow S_{0}$ optical transition moments have quite different orientations in the respective molecular frames. The results will be interpreted in the framework of a state-mixing model for the $S_{1}$ states of the two molecules. URI: http://hdl.handle.net/1811/13949 Other Identifiers: 1997-RE-10
