Abstract

We study large amplitude motions of methyl group in 9-methylanthracene (9MA) by high-resolution spectroscopy. 9MA molecules are delivered in a supersonic beam and are excited by a single mode Ti:Sapphire laser. The frequency of the laser is controlled with reference to an Er doped fiber optical frequency comb. The figure is the observed rovibronic spectra of S$_1(0a_1') \leftarrow$ S$_0(0a_1')$ and S$_1(1e'') \leftarrow$ S$_0(1e'')$ transitions. Although the two transitions are overlapped, the rotational lines are well resolved. Now we try to assign the rotational lines and to analyze interactions in the vibronic excited states. \begin{wrapfigure}{r}{0pt} \includegraphics[scale=0.6]{Misono20_a.eps} \end{wrapfigure}
