摘要
本工作结合多光子离化谱,激光诱导荧光及荧光激发谱技术,仔细研究Cl_2分子高激发Rydberg态和混合Rydbery-价态的结构及性质,定域了1~1∑_u^+态内区的位置,证明2~1∑_u^+态强的Rydberg-价混合特征,发现一新的u对称性Rydberg态并建议标识为~3∑_u态的激发,对三光子激发过程,2~1∑_u^+与1~1∑_u^+态间的相互作用及三次谐波效应对光谱的影响作详细讨论。
The structures and properties of highly excited Rydberg and mixed Rydberg-valence states of molecular chlorine have been studied in detail by combining ioniza-tion, excitation and fluorescence spectroscopic techniques following multiphoton exci tation. The position of the inner-well of l1∑u+ state is located, and the 21∑u+ state is found to exhibit a strong mixed Rydberg and ion-pair valence character. A new series with symmetry is discovered and a assignment to the excitation of Rydberg state 3∑n is suggested. Based on the experimental results, the processes of three photon excitation, interation of 21∑u+ with 11∑u+ states and spectral effects of third harmonic generation are discussed.
