We have obtained high-resolution Fourier transform emission spectra of the à left and right arrow &Xtilde; transition of the jet-cooled p-xylyl radical in the 450-nm spectral region. The band contours of several vibronic bands are examined. By using the rotational constants obtained from previous high-resolution LIF spectra and information about the torsional constants from dispersed fluorescence experiments, both a-type and b-type band contours are simulated. Based on symmetry arguments and the results of the simulation, we have reassigned the 6a and 6b vibrational mode frequencies of the ground electronic state of the p-xylyl radical.

我们已获得在450纳米光谱区域内喷射冷却对二甲苯基自由基从Ã向左箭头&Xtilde;跃迁的高分辨率傅里叶变换发射光谱。研究了几个振转带的带形轮廓。通过使用从先前的高分辨率激光诱导荧光光谱获得的转动常数以及来自色散荧光实验的扭转常数信息，对a型和b型带形轮廓进行了模拟。基于对称性论证和模拟结果，我们重新确定了对二甲苯基自由基基电子态的6a和6b振动模式频率。版权所有1999年学术出版社。
